a while ago, i was messing with my overboost regulator from ITP and i messed up the setting on it. I got it so it wont set an overboost code anymore, but i got some strange readings from my scangauge reguarding boost pressure.
Once it goes past 22-24 psi on the scan gauge, it reads -28.9 psi for the rest of the WOT run. Does this mean the truck is defueling, or must it set a code in order to "defuel"? I suspect since it is reading -28.9 its not "adding" anymore fuel, correct?
