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

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!

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.
