yeah. the check engine light only comes on in extreme situations. usualy when it defuels it just kinda starts to fall on its face. my truck does it prety bad. the rpms go way up and then it will actualy produce less power the deeper into the red line I go.
Mine would only start letting out after the light went on. If it starts to defuel at 20-21psi, why would the overboost annihilator be set to 22psi? They want you to defuel for just a sec? Probably because it doesnt start to defuel til after 22psi
