how much boost do you go over stock before an overboost code shows up, and when this happens does the truck de-fuel itsself. my next question is do the boost fooler before the j-hook. thanks guys

 

Your superchips should boost fool already. Not sure when the code is tripped. And I am not sure if it has to be above a certain boost for a certain amount of time. But the factory ECM will defuel around 22psi. I am guessing it would trip a code close to this value.
