Drove all the way from Omaha it was a 4 hour round trip but worth it! They fixed our vehicle after another tuner put a bad tune on it. We are definitely planning on taking our vehicle back for more fun things when the time is right!

Called and had a few questions about an STI that a buddy purchased from a dealer with not much info on it. Grayson was extremely helpful and super friendly, answered all my questions. If you have a Subaru, these are the guys to call.

Even though they weren't able to upgrade my exhaust (car is still under warranty), they were very informative in educating me on what upgrades would be beneficial in the future.
