Has anyone had an overboost issue. My 2001 has the P0234 over boost code. I have nothing done to increase boost .Juice/ A2 & exhaust This seems to happen only on a performance setting and not on the stock setting both with the banks 6 gun and the Juice. Is there a sensor I can replace? Does this 01 model have an EGR valve?
This truck only boost up to aprox 24. When code came on it was at about 6psi. Just freeway driving (empty).
