Mike, I have the Diablo Sport Predator for my SS. I have purchased and installed a K&N CAI, Magnaflow Comp. Series Cat-Back exhaust, and will install a set of American Racing LT Headers soon. What can I do as far as the tuning aspect after the header install? I know I will need a custom tune to account for the lowered back pressure to meet emissions but I was wondering if there is a cost efficient way to do this.
I know that Custom tuning requires hours at the dyno but is there anyway to bypass this? Any helpful information is appreciated. Please make any additional suggestions even if not mentioned. PM please. Thanks.
