I am swapping pulley to a 3.5" and expect to see around 21 lbs of boost. The question I have is in regard to the the spark table cylinder airmass maximum range. The stock table maxes out at 1.36 (g). I am already running about 1.6g and I am anticipating 1.8-1.9. So my question is, should I modify the header on the spark table and change the increment from .04g to maybe .06g to increase the max closer to where I expect to be running?
