Very disappointed with my experience at Finish Line Performance. I waited 3 months for a tune, and from the start, it had issues. Several sensors that should’ve been turned off for my setup were left active, causing drivability problems. Instead of taking accountability, he blamed the person who picked up my car — which had nothing to do with the poor tuning. On top of that, when I reached out about the ongoing issue (which he knows is caused by the tune), he makes it extremely difficult to reschedule or get it corrected. He also claimed the car “only runs good on his dyno,” which defeats the purpose of a proper street-ready tune. After all the time and money spent, the lack of ownership and professionalism is frustrating. Wouldn’t recommend based on this experience.

I took my Impala to Finish Line Performance to have the EFI adjusted. Dan spent several hours making sure the settings were correct before even working on the tune. How's attention to detail is incredible. Thanks Brad
View on GoogleThe best performance mechanic around Chicago land/NWI. Dan's knowledge on older cars is incredible. Built my 95 Lt1 Corvette and dyno tuned it, he is also one of very few that knows how to tune Lt1's. I highly recommend him for anything that requires an experienced mechanic in performance cars.
View on GoogleI brought my 1971 Oldsmobile Cutlass in because of braking and electrical issues. Dan is a very knowledgeable and great with working on older muscle cars. He fixed both issues AND wired up and mounted the switch for my exhaust cutouts. Everything looked nice and neat. He took the time to explain to me everything he did. Great experience and will definitely be going back for future upgrades. Bob McCarthy Joliet IL
