well when i installed the charger i did it myself, and i never read anything about changing the plugs. there was no mention of it in the manual(even though i put new 1's in about 6 month before the install). any recomendations on what plug to use and what i should gap it to. i'm running a cheapass powerdyne @6lbs but i have a 11lb pulley that i may swap in. i even had the car pro tuned and they made no mention of the plugs to me while tunning on the dyno.
i think they retarded my timing like 10degrees & told me if i hear any detonation go to 11 degrees. it sounds like an awfull lot of timing taken out for only 6lbs of boost.
i am still running stock injectors w/an inline boost pump. could this be my problem?
when i say detonation i hear it under full pedal (a very slight ping or rattling).
