I did a search and really no specifics found. On the Predator what's a good timing setting for a basically stock lightning with CAI and Cat-Back on the 91 octane tune?? So far I like the differences it has made and I got my shiftpoints and such all dialed in. Just curious if I should play eith the timing, Global or otherwise... How about Mas Air & Fuel?? Any quick adjustments that may give me that extra edge?? Thanks! any info helps, BK :thumbsup:
