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!

Ben and his crew over at EFI are the best in the business. They’ve not only allowed for me to leave happy with my newly tuned car, but have also given me nothing but awesome customer service from the beginning to the end. Whether it was an email, phone call, or even talk at the shop, the guys over at EFI were more than willing to answer any questions, give insights about the car, or anything car related in general. All in all, super happy with my experience.

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.

I have brought by car to EFI for any help I have needed for over a year now and I couldn’t be happier with their work. Honestly I feel bad I haven’t wrote this review sooner. Since the beginning they have treated me like family. They have a great team of guys who are very knowledgeable and do great work. Ben and I have sent countless texts to each other helping me out figure out what parts and I need and the best parts for the power I want to make, I could go on and on about how much they have helped me but bottom line if you want to get work done on your car or a tune and want personalized help and people you can trust look no further EFI are the guys to do it!

Brought in my GR86 for a differential swap from a 3:9 to 4:3. Work was done quick and efficiently. I even got a little tour of their facility. Super knowledgeable and friendly team. If you are in the New England area I recommend reaching out to EFI for anything and everything Subaru.

I was buying a 04 Miata to start autocrossing and EFI was helping me before the car even got delivered. Helped identify known NB issues, (rust lol) and installed the aftermarket parts I ordered. Great service and great prices, well done.

Great group of people that provide quality work on Subarus. Provided informative diagnostic info to make a tough decision on an STi and were extremely helpful, flexible and understanding.

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.

Brought my wrx in for some work. Clutch and carbon cleaning. Ended up getting a dyno tune as well to fix some of my running issues on the car. They are fast workers, they keep things honest and I would definitely recommend them and trust them with your car. My wrx is running great. Kyle is also a really easy going guy and helped me through email the whole time. Thanks again guys.

These guys know what they’re doing. Much as I’ve owned three Miatas over the past 35 years, I learned a wealth of new info on my very first visit. If you own a Miata or Subaru and live within driving distance of their Bethel CT shop, these guys are a must!

EFI Logics is hands down one of the best performance shops I’ve ever worked with. From the first interaction to the final results, their professionalism, knowledge, and attention to detail were absolutely top-tier. The team clearly knows Subaru performance inside and out. They took the time to explain everything, answered questions thoroughly, and never made me feel rushed or upsold. Their recommendations were honest and based on what was best for the car, not what was most expensive. The quality of work speaks for itself—clean, precise, and done right the first time. The car runs flawlessly, performs exactly as expected, and the tuning is smooth, powerful, and confidence-inspiring. You can tell they take pride in their work and genuinely care about the end result. Communication was excellent throughout the process, timelines were accurate, and the shop itself is organized and professional. If you’re looking for a place you can trust with your Subaru—whether it’s maintenance, performance upgrades, or tuning—EFI Logics is absolutely worth the drive. Highly recommended. I wouldn’t take my car anywhere else.

I have been bringing my 2004 WRX here for about 6 years now and drive 1 hour one way! Great customer service, amazing techs, a great tuner and most importantly a down to earth environment. The car is daily driven and auto-crossed so that should tell you a lot.

Got my ND Miata aligned here. They got the alignment spot on to what I requested and even provided some feedback to my original request based on their experience. I'm glad I listened because it feels fantastic. They also adjusted my coil over height perfectly too. Very comfy waiting room sofa as well.

Long term review update. These guys are the absolute best. Admittedly I messed up and they were so helpful fixing it on the Dyno. I got my built motor big turbo legacy GT tuned there 5 years ago and it still runs absolutely perfect, still smoking vettes and stangs in my family sedan. I traveled 5 hours 1 way for their tune and I'd do it again. Best shop on the east coast without a doubt
