If your engine's electronic control module (ECM) has a delay activating your Pacbrake exhaust brake, the Pacbrake C20135 ECM By-Pass System may be the answer! This Kit will reduce the delay in activating the exhaust brake by more than 50%! Another great feature is when you overshoot your cruise control set speed, the ECM By-Pass will automatically activate and slow the vehicle to your preset cruise speed!
