dajogejr Posted June 24, 2009 Report Share Posted June 24, 2009 What is your elevation? At or near sea level, I'd stick with .015 to .020 max. Quote Link to comment Share on other sites More sharing options...

mopar1rules Posted June 24, 2009 Report Share Posted June 24, 2009 (edited) if i recall from my TSR sheets, .030" off is safe for 91 octane, w/OEM exhaust port. i've got .030" off w/no problems....i'm @ sea level too.
