RE: Low boost PSI I believe the code was a 2636 “VGT Actuator- abnormal update rate”. Actuator does not calibrate with old actuator and with a brand new one. Mechanic checked wiring made sure harness was good from the ECM to the Actuator. Had the guy that demandated my truck take a look at it and he said nothing was wrong with his programming but idk that for a fact. He put a different program and truck runs the same. Lift pump won’t come on as well. ECM was set to factory settings and VGT still would not Calibrate. | |||
