im using a 91 octane Tune from james at henson performance and was wondering if there are any adverse effects on my engine from advancing the timing...i tried the maximum which is +4 from 0-2000 rpm,+4 from 2000-4000 and +2 from 4000-8000...i noticed alot more low end power and i like it..but i dont know if its good for my engine..anyone out there with knowledge on advancing and retarding timing.
