Marbles loose in the engine o.k. guys, i got my car dynoed last week with 15k miles on it and only a lid/k&n and while on the dyno, for the first time, i head helacious (or what i thought to be) pinging from about 4500rpm on. sean at fastech said that this type of detonation was typical on most of the ls1's he's seen, and i could get different spark plugs (TR6's gapped about .38) and it might help. well i don't have time to do that right now, but i've been putting in a little bit of octane boost to reduce the pinging. the dynograph shows the detonation starting around 4200rpms.
i just got this car 2 weeks ago and my last T/A didn't have this much detonation on the dyno. with the windows rolled down and the engine under load, it pings every time above 4500rpms. help me please....what can i do?
