Absolutely the best place to get work done on your car! Had some upgrades done and they exceeded my expectations. Tony does a great job communicating and sent updates throughout the process. Outstanding customer service. If you need work done Speed Inc is the place to go.

I had a ZL1 in need of a tune and Speed Inc did a great job getting it dialed in. It had a decent amount of modifications and I didn't have the exact specs and they were still able to get the vehicle dialed perfectly. First time dealing and wont be the last. Thank you guys. Abe - Peoria Motorworks
