I bought a 2005 Lly duramax a few months ago. When I bought it there was a bad transmission in it. I swapped it out and everything seemed fine. Shortly after I swapped out the water pump and now that its back together I have little to no throttle response. I can floor it and the rpms will go up slightly but the truck doesn't really accelerate. Its worse when going up any inclined. I've replaced the fuel filter. The truck is basically stock other than banks tuner and 5" exhaust. Any help is appreciated. Thanks

I am on stock tune and have no cel on
Check the wire harness at the side of the alternator, the sharp corner, where it is tied down, cuts into the harness and shorts the wires.
This will cause problems as you describe
