So over the time I have had this truck I have had some issues. I am getting a trouble code with the wastegate solenoid, So I have done the wiring tests and checked for resistance and it shows up okay. So I am starting to wonder if its the Wastegate its self and its not boosting right or is limiting the boost? Or Should I replace that solenoid? I have that the error started after I have fixed the clutch fan cable. I haven't replaced that fan yet but I am going to soon. I have a bullydog gt tuner if that makes any difference..

 

Moved to the diesel section. Hopefully you will get better responses here.
