This customer wasn’t satisfied with the audible knock he had from his previous overzealous tuner.  He drove in from Virginia and we installed our Purple Belt Performance Package.  This car now makes 491 whp and 518 wtq on 93 octane pump gas and 597 whp and 551 wtq on E46 fuel.  Best of all, the tune is safe and solid, with no knock whatsoever.  We do it right.

This customer drove all the way from Texas to Ohio so we could put our magic touch on his 2016 ATS-V.  He left our shop with 609 whp and 612 wtq on 99 octane plus methanol injection, and 662 whp and 716 wtq on E54 with methanol.  This is enough power to run nines in the quarter mile!
