The guys at EFI did a great job with my mustang! They did some exhaust work, got me tuned, and running like brand new. Highly recommend EFI!

EFI is beyond incredible. They’ve been taking care of my Audi’s for a while now and each time I work with them it gets better. Will is amazing to work with! Each time I need these guys whether it’s for basic maintenance or performance, I don’t have to bat an eye or worry about anything possibly going wrong. Incredibly easy process start to finish each time. If you have a foreign vehicle, Audi/BMW, you’d be crazy not to give these guys a shot! Thanks again for treating my Audi like it’s your own, Will!!!

The team at EFI is nothing short of incredible. They can do it all; with detail, precision, and humility. Had a ton of work done to my A6 TDI including a mean stage 1 tune, full front suspension upgrade and transmission service. Was so happy with that, went for a Stage 1 ECU mapping on my S63 AMG. Both sensitive and uncommon platforms to modify. The gains were immediately apparent! Throughout my communications with the service managers and owner, it became clear those numbers were backed by real experience as well. True enthusiasts, true modern motorheads with a love for what they do. Come check them out

No, they sucked. Did not clearly state they were guessing my ABS module was bad in my 93 S4 and ABS still inopp after replacement of my original ABS module. $1000 ultimately wasted.

Purchased a car listed by EFI Motorsport on BAT and flew in to collect it. Car was exactly as described by Marc and performed flawlessly on the 750+ mile drive home. Looking forward to doing more business with them in the future! Thanks again!

Excellent service and very knowledgeable. My car would be a lawn ornament without Mark and his team.

Marc, Will, and the team are true professionals in a world full of sketchy know-it-alls. My C4 S4 requires a special skill set to tune and modify, expertise that the team at EFI have in abundance. They were able to efficiently diagnose my car and come up with a very accurate quote. They work in a timely manner with excellent customer service and communication - something that lacks in other shops.
If you drive a old Audi, new Audi, European, or specialty car, you can trust that EFI will take care of you.
Having been in the automobile service industry my whole life, I can say with much confidence that this shop embodies the rare and exceptional qualities going beyond good work and attention to detail.

Marc and the team at EFI have been an unbelievable resource for me. I have an obscure old Frankenstein of an Audi 90 that spent some time with them. EFI has a dyno system in house, Marc is notoriously the man to tune in the region.
They have the expertise, the resources, and the patience to really solve problems. I have even bugged them in a pinch and they come through always. I can't thank them enough for making my crazy car a reality and keeping it reliably running.

Can't say enough great things about this shop. I recently had my A4 B8.5 in for service and they did an extraordinary job with everything. Had Timing Chain, Balance Chain, PCV, Transmission Flush, Ignition Coils, Downpipe, Rear Pads/Rotors, Front Pads/ Rotors and Calipers, Front Upper Control Arms, Drive Belt/Tensioner, Oil Leak, Rear Coils Springs, Rims and Tires. Will was extremely knowledgeable with explaining all the details, quotes and answering all my questions. Great prices, customer service and outstanding work. Definitely will be back for more maintenance and performance mods as well.
