Chipping a diesel is a whole different WORLD than a NA gas motor. There's no boost level to raise, there's no EGT limit to ignore, there's no diesel NOX emissions to completely disregard.
All you can do in a gas NA app is to give a more aggressive timing curve, change some fuel parameters, and reprogram the transmission shift points.
With that said, there will be lots of aftermarket goodies available for the C6. Nothing's available yet cause there is ONLY ONE C6 in the world right now. Makes it hard to cut and fit your aftermarket accessories for it.
