Cleared codes by disconnecting both batteries for a couple minutes. Then when I start the engine the ses light comes on and stays on till I shut it off and restart it then light goes out and stays off.

I bought this truck a few weeks ago and the turbo was shot. Replaced turbo with GM8 and now have boost. This truck came with cold air intake,PMD with fsd cooler installed on intake, boost gauge and egt gauge. How can I tell if its been chipped? Also has 3.5 down pipe and 4 inch exhaust.

Besides having a shot Turbo, What were the symptoms you were getting?

I have gotten codes 25 and 35 and suspect either a faulty PMD or an APP. Where I am, APP are over $600.00 brand new
