Went with my brother to get his '18 WRX dyno tuned and it went great! The mechanics are Subaru wizards and the tune really transformed my brothers WRX with real performance gains that are reliable and maintain the driveability of the car. If you are serious about automotive performance and are ready to take your car to the next level you owe it to yourself to go to EFI.

Huge thanks to the guys over at EFI taking care of me these last couple of days got my new intake, injectors and tune done and chased down a misfire on the dyno pulling a late night to make sure everything was good to go. The guys are super knowledgeable in there and will help take care of you during unexpected problems. A all around amazing experience doing business with them would not take my car anywhere else!

Words can not express how satisfied I am with the work EFi has done to my FXT. I have been wanting to do a 6 speed swap for a long time. Doing tons of research, I decided to go with a JDM Forester STi 6 speed. EFi Logics was referred to me by a few friends, including Sam at Jspecauto where I obtained the 6 speed. After having a lengthy convo with Pete at EFi, he gave me a very reasonable estimate and we came up with a game plan. Not to long afterwards the car and parts was delivered. Jack took on the challenge of my swap. He went above and BEYOND any and all expectations with my car. He was extremely meticulous with this swap. Every single thing was addressed. Transmission. Axles. Seals. Hubs. Studs. Brakes. Rotors. Sway bars. Control arms. Lateral links. Ebrake. Ubrace. Subframe. Struts. Springs. Steering rack. Drive shaft. All of it. Not only was the work top notch... the customer service was too. The communication from the team at EFi Logics was very comforting. Pete. Jack. Ben. Will. Cory. They all kept me in the loop as to what and why. I couldn't be happier. It was worth every penny and then some. They gave me the best estimate and I am quite satisfied with the job. The customer service didn't stop after I picked up the car. I ran into a problem on the road. I called EFi and within mins Ben, and Jack were there to help me. Jack addressed the situation on site, got the car to the shop and quickly fixed the problem. What made that more meaningful to me... was the issue was not related to the work they had done previously. They simply wanted to be sure I was ok, and was back on the road enjoying my car. It is refreshing to see this level of customer service still exist. I recommend EFi Logics to anyone looking to do upgrades on their car. From simple, to Extreme. In a time where the market is flooded with quite a few qualified shops that specializes in similar work. I am glad that I chose EFi Logics. They were very patient with me. Answered all questions, and addressed all doubt in my mind. I am looking forward to finishing my build with them. If anyone has any questions about my swap... feel free to shoot me a PM. I have tons of pictures as well. I'll be more than happy to share my experience. Thank you EFi Logics.

I picked up my car from EFI yesterday, and I cannot believe how impressed I am with everything they have done. I had originally gone there for some forged pistons and TGV deletes, but cylinder 2 was in real bad shape, so I got a new block. Rob really knows how to do some excellent work, everything was cleaned up nicely in the engine bay... it looks brand spanking new under the hood. The engine runs so smoothly like it was brand new, even with the forged pistons in there.

These are the kind of people you want working on your car. Everyone there takes the time to talk to you about the work they have done on your car, they treat you with respect and all of them are friendly. I really enjoy going there to have work done on my car.

I have once again experienced the pleasure of dealing with one of IWSTI's best vendors.

EFI logics is a shop that removes the "guilt" from parting ways with my hard-earned money by providing me with hard-work, honesty, professionalism, and skill. They don't waste my time.

Many of you know that I am tough on my critiques of shops/service providers because as a community, I feel that we owe it to one another to reward or punish vendors by giving or taking away business according to the way we are served as individuals. This is what provides us leverage to make or break vendors.

EFI has consistently provided top notch service and products to me and other members of this community. Today was just another day I was reminded of their abilities.

If you are looking for a shop to get your work done right at, there is no question this is the place.

Thank you, EFI Logics.

EFI Logics is the best shop in the state of CT. Pete and the entire staff are super knowledgeable not only on the Subaru platform, but any brand car you bring to them. The service is excellent and I can rely on any one of the mechanics there for spot on diagnosis and repairs. They built my STi in 2015 and it's been solid every since. Whether you need repairs or advice on a build that you want to do, give them a call to steer you in the right direction!

My car was tuned here years ago by Mike Botti. Tune felt great. Great power delivery, no flat spots, areas needing attention or problem areas. Staff here also great. Blew a vac line on dyno. All the mad scientists crowded around to give my '12 wrx the fix it needed to continue the tune. Some shops would just say.. come back when its fixed! And quite possibly charge you anyway. Not these guys!
Thanks!

Now when I tell you that EFI has in my opinion the BEST customer service and the BEST techs, it's because its 110% TRUE. Rob inspected my car top to bottom, front to back, and made sure he could find out what the hell was going on with my car. Chris and Jack even came over to lend a hand and help diagnose the issue. I mean Chris had a car on the dyno, Jack was finishing a clutch install and they all made sure my car was taken care of. Now they didn't leave the other customers on hold or anything, there were a few things going on with those cars as well, which let them take a few moments to help me. After about an hour, Rob pulled a code saying cylinder 3 was running lean...being the awesome guy that he is, he checked my plug, tested a coil pack and bam, I had a bad coil! The whole time I was really calm about the whole thing. I think it was because I knew my car was in good hands and if it was something HUGE to fix, It's not like I didn't get 60k miles out of it with 6 different turbos I owe the team at EFI Logics a lot!! I could have easily been told that my car needed to stay a few days to try and diagnose the issue, but they would not stop until they found it! It was Saturday, cold as you know what, and already close to 3pm. Chris was generous enough to let me borrow a coil to drive home, I mean c'mon he's the best!!! Even though he hates my car, he likes taking care of me and I appreciate it more than anything. I was so excited, said my goodbyes and was on my way home...

I was in a crash in April and really screwed up my BMW and needed a serious alignment. These guys were recommended to me by a friend and hands down the best recommendation I have received since tracking this car. These guys are the best performance shop I have ever worked with. They aligned the car to my specs , they walked me through the whole process, made recommendations , helped me learn more about my car and by far the friendliest guys I have met in the last few years. Thanks and keep up the great work.

John D.

Very knowledgeable staff. Helped with my needs.

EFI Logics is the place to go for everything to do with a car. The owner Ben is amazing. The mechanic Mike, is very knowledgeable. The tuner Calvin is very good at what he does and knows what he's doing. Honestly this business is the right place to go to.

helal E,

Came in today to do an APR tune on my Audi S3.
Was in and out in a little over an hour. Cool waiting area with racing games and car magazines. They specialize in Subarus but did a great job with my Audi and very professional. Car feels amazing now.

Josh B.

Absolutely 5 star. Set up a time to bring my 2021 STI in for small parts install as well as a tune. Ran a few min late due to traffic and they basically had someone outside waiting to bring my car in to get started. Staff was laid back and knowledgeable. Tuner was on point with what I wanted with my car. Car runs like an absolute dream right now. Will be back here for a re tune when future upgrades come no doubt about it. Also very reassuring seeing a ton of Subies outside while pulling up for the 1st time.

J Nz

Everyone so helpful. Spent over half hour going over all options for tuning and modifications. Pete and the guys are only place I will trust my Subaru with!

Professional and knowledgeable staff that provide a quality and enjoyable experience. I couldn't be happier with the results of my visit and cannot say enough good about the shop as a whole. I wouldn't hesitate to recommend to friends and I look forward to working with EFI Logics in the future!

Jason J.

Everyone there was super friendly and cooperative with me. There were some issues that needed to be addressed with my car and with my permission they fixed them quickly and correctly. The tune they put on feels great and my car runs much smoother than before. I would definitely recommend this place for anyone who wants performance work done to their car!

Liam G.

Great shop and they know their stuff!

Went in for a APR Tune on my 2010 VW. Excellent service, knowledgeable mechanics that love and respect cars. Had no worries in there quality of work. Truly A1. Thanks guys.

Will K.

Pete, Matt, and Ben from EFI are top notch. These dudes know what they're doing and they are the sole reason my STi is still on the road today. Super patient with any issues I've ever had and they are always transparent on cost/time with each job. Give em a visit or a call and you won't be disappointed.

Travis K.

Got tuned by Chris @ EFI. He smoothed out the boost, made it come on a lot quicker, and stay on longer. He used a new Autocross specific map he's been working on as the shop cars are dedicated road racers meant for top end power. Spent at least 1.5 hours on the dyno and then went for a cruise where he made a few minor tweaks. All in all, we started around 11:15am or so and finished up a bit after 2 pm. Chris said it was one of the highest wtq stock turbo 06's he's tuned. Definitely worth the 8 hour round trip drive.

11/14/08 efi tune here. (305/325). First off, Chris accommodated for my time from showing up a little late. Then he was very focused in getting the absolute best tune out of my car given my mods and whatnot. The tune fixed some bucking and surging issues i had on top of smoothing out the ewg i just installed. Not to mention the extra power from my last tune with him. Overall the car pulls amazingly for a daily driver and I absolutely love my sti more now because of Chris' magic. Great surrounding atmosphere, cool new shop, and quite possibly the best tuner around. I will keep coming back to EFI whenever I need and if your thinking about going then I highly recommend it. Whether your a daily driver looking for some extra mpg, or a track/race setup, then go to EFI! BTW, Chris will answer any of your questions as he very informative and caring about your needed or performed tune and even making sure that you enjoy it afterwards. Thank you once again Chris!

Chris is one of the best tuners that I have talked with via PM. He's a really nice, logical, talented guy - unlike a lot of other 'professional' tuners who are basically there to just make money (and don't really understand how to tune).

I visited Chris at EFI and asked him how I can get 340whp and to paraphrase he said "18g ebay TMIC/injectors for 325 whp on his MUSTANG Dyno..which reads 10 or 15whp less. This is the route I am going to take with Chris next spring. By the way his new shop in Bethel Ct is very nice and it is coming together beautifully. Chris had Jack do the install on my Bilstein set up and I am very satisfied. Jack did a great job super clean shop too. We did a few dyno pulls and all is good under the hood. If you are in the Tri-State area go to EFI they are nice people and everyone knows their reputation.

Ben and his crew are top notch. Customer service level exceeded all my expectations. I run a service department as well, and know the day to day challenges. 100% recommended for any of your daily driver or high horsepower needs. These guys do not disappoint!

Pete/Ben/Jack were helpful in discussing what I wanted to get done and recommended only the necessities for a Stage 2 upgrade (power/reliability) for my MY'18 Subaru WRX. Matt was great and cruised with the install on the car and had it setup on the dyno - where Calvin/Ben had it tuned to the best of the car's capability to handle the mods.

reasonable pricing, good facility and chill dudes all around! will definitely be heading there for future work.

Seeking new shop that is nearer to me than driving for 6 hours, and i feel like I've made the right call. Put up with me there all day, friendly, communicative, tolerant, what else can i say. EFI is my cars new home. Did a full exhaust switch for Focus RS, sounds way to loud and i love it.

I have a 16 sti (270whp 77,000 miles) I brought my car to the guys at efi to tune my car. Since then I've driven 24,000 miles in 2021 from 13,000ft to -282ft and my car is extremely happy. Just the last two days I've driven from New York to Frisco, CO worst knock? -1.40 the whole trip. They are more than willing to answer questions and now no matter where I am in the US my car will be retuned by them

Mitch Howell

EFI was very friendly and helpful even when I called them late in the afternoon because my Subaru had problems getting into boost. I stopped by and they were able to get my car back up and running normally very quickly. They are very knowledgeable and educated me on things to keep my eye on. I will certainly bring my car back in the future!

Billy Gallo

Came in with my '18 WRX as I got lazy diagnosing why my intercooler wouldn't fit on correctly after installing an IAG Street Series AOS. Not only did they visit the intercooler fitment issue, but they went through everything I had previously installed and cleaned it up to top shape. They were also kind enough to take a look at my brothers '08 STI which he had recently acquired and helped highlight everything that would have extremely burdened him in the future. All throughout the process, the guys at EFI were extremely professional, kind and very down to earth. Everything I would expect from a shop dealing with modified imports/domestics. Special shoutout to the guy who checked me in upon my arrival (sorry I'm bad with names), but he was significantly taller than I am. Would definitely recommend EFI Logics to anyone in the tri-state. Will definitely go there for futures needs such as tuning/service and relay the message to friends.

Danylo Crawford

All I have to say they made my car pull hard and strong one of best tuners out there. I drove 2 1/2 hours from New Jersey to them and well worth it. Made so much horsepower and torque to the wheels on my setup that now I have to get used to my car. Enough said I'm taking that drive again when I put a bigger turbo on my speed3. Car feels different rides so much better and the pulls are really strong. Almost feels like a new car off the dealer just with a punch so keep up the good work EFI and hope to see you again next year for re tunes

D3ath Strike01

Where to begin.... I have been having issues with my subaru. I had some work done by a local dealer and the refused to help me with my issues after working on my car. They claimed that they couldn't work on it anymore because it was "modded". Which wasn't a problem for them initially. So still having problems I figured I would try EFI. Thank goodness I did. They went over the work the previous shop did. Terrifying. RTV for gaskets that I paid for, over torqued timing and cams and much more. The knowledgeable and professional people at EFI saved my car from becoming the ticking time bomb that the dealer left me with. Without a doubt... this will be the only place my car goes for service in the future. Thanks again!
