ive got a zc with a greddy kit without intercooler.the timing is set at stock.the car runs way rich.im going to put new plugs in and i was wondering if i could go with step 5 plugs to burn some of that fuel.the boost is set at stock although my gauge reads 10psi(autometer crap) any info would be apreciated.

no. get it tuned instead.

hotter plug = detonation.

do it right the first time cuz its likely you wont get a second chance.
