Ive got a client who wanted a c6 vette really fast and I made it so. D1X, ported heads, intake, big tubes, ID1300's Foremotive pumps with Boost reference, etc. I can drive it but I have an honest fear of him having a drink and killing 2 people. A C6 is like a flat bottom drag boat. its making 15lbs of boost and I am going to guess your gonna say lower the boost. Well I am going to street race it, so id rather just put big tune back in it. I guess a traction control increase, but I hate a sudden retard of timing on boost. As I am typing this I guess I could change throttle open percentages in all gears? Its got the new Nitto Drag Radials on it. They help but not enough bite. How do you lower the power by like 300 hp for a guy that has no experience but the deepest of pockets?
