A IAT MOD TO BUMP TIMING JJENNINGS!?!?!?!?!?JJENNINGS, you just explained your ping issue. That's not the way to correct timing on a motor with so many mods. Quit it, now, or you'll be singing the Buckshot blues. If you hear pinging, damage is being done.
PA, sounds like you're back to being the only one with a real ping issue... Just wondering, does it do it at all when the engine is still cool?
