My car is a Na-T with a 67mm turbo. I have all the supporting mods but I don't know how much I should retard my timing to run 18 or higher lbs of boost. I am using the afc/vpc combo. Since my base timing is 10 and na's have 22 deg of advanced timing (I think). How much should I retard my dist to be on the safe side. Is there a general rule of thumb when applying boost and timing? My Intake and Exhaust is still set on 0. Thanks for the help
