I think Im getting a little closer to finding a map that works without all the decel popping. Today I tried 602 ,596 ,and a few others that didnt work so well. I then tried 0600 and it worked the best. With 0600 I didnt have popping between shifts , and yes I do let off the throttle all the way between shifts. Anyway I tried #23 on 15 and 16 and still had popping , then I put #23 to 50 and it quit a great deal. Only have a small amount of decel popping. So for this is the best it has done in a long long time.Im running the stock plugs and will put in my Screaming Eagle Triple Platinums to see if this helps. It seems that Im only off on the settings by a few numbers.Im running Cycle-Shak slip-ons in case anyone else has any other maps they tried.
