Only 91-95s lt1 tuner around. Hands down the best also.

Best performance garage in IL, period!

I like Finish Line Performance because Dan educates you on the issues involved in tuning your vehicle. He does a thorough job as hes completing the dyno test at a safe pace.

Great place to get your car worked on! The guys there are awesome and really cool they worked with me really well specially when I needed extra parts and they know there stuff mechanically very well!

Great place. Had my jeep tuned for a modified motor and a supercharger, runs like a champ. I am so happy I went there. Going to bring mt 1937 plymouth there when its time for tuning.

Had a cam installed on my 2012 camaro by another shop and never really was satisfied with the tune. Took the car to finish line about a year ago and Dan said he thought he could make the car run much better. I decided to have them install a rear diff 3.70 gears and tune. Very glad I did. I am now a year in and couldnt be happier on how the car performs. Dan did a great job tuning and Tony was very responsive to all my questions. I will be going back.

These guys are great, very diligent and knowlegable. Dan Worked on my 74 Nova and took great attention to detail. Tony kept me informed at every step. Ill be there again son

They have been taking care of my 96 Grand Sport for the last several years. They are very diligent about finding the right parts, do clean work, and always deliver the car with no issues. I love these guys. Best dyno service in Chicago

HORRIBLE!! STAY AWAY. I dont know how theyre still in business. Car is WORSE than it was before I took it there for engine work! Cost me an additional 800 to have car fixed at a reputable shop. Youve been warned! Dont make a costly mistake like I did!!

Finish Line Performance is the place to go if you need expert High Performance Tuning, Service, Installation or Advice for your Car, Truck, or SUV.They have kept my one owner 2000 C5 Corvette with its 1,000HP 427 Blower Motor on the Drag Strip for 15 years, and 800 9 second runs incredible as that sounds its true! UTube Search John Reese Barbie Corvette for video proof - Thank you for a great relationship over all these years!

The support we received while they dyno tuned our car was top notch!

Finish Line does amazing work, Matt the owner is so patient and personable, I HIGHLY recommend this company for all youre mechanical needs!!

Warning!!! do not go here, messed up a 350 small block engine putting in new heads, bunch of money hungry losers. go else where, not much knowledge, 350 chevy small block easiest to work on, had to get car towed home after i left there place, would not even give partial refund go to last chance auto more knowledgeable

Great to see that the same person is writing multiple bad reviews under different names.
