The 3Gs need some serious ignition retard help. I did a RIPP mods supercharger on a GTS and it was detonating like crazy. It was one of the early pos kits with too small of injectors, no fuel pump and an HKS AFR that didn't do anything for fuel control. They now have a black bo out for it that can handle fuel and timing, but they won't sell it seperately to turbo guys.
We tried tuning Peters turbo 3G, but even with turbo friendly compression, big injectors and an E-manage controlling fuel it would start audibly detonating hardcore in the 4000RPM range at what should be an acceptable boost level. Some sort of timing control would fix the problem, but nothing seems to work on the 3Gs besides the RIPP black box which they won't sell. Even with low compression, you can't run the kind of timing that an NA car wants to run at a halfway decent boost level. You also can't let the stock knock sensor try to control timing for you. You want to pull timing out before it starts knocking and if you can actually hear a turbo car detonating then you have some problems.
