Truck has a cold air with a k&n and a cat back. I needed experience with a gen 4 so i had a look see. after i re curved the maf I tried to give him a few degs of spark truck always runs 89 octane but it looks as if if does not like it. I did tame the p.e down to 12.5 and pulled out a deg of timing per my spark retard histogram. This is not the final scan because my laptop died but the spark acted about the same. I didnt get it as often but i always got in when entering p.e.
Your insight will be much appreciated.
