Just did a standard rebuild, rings, bearings, lifters, gaskets, and had a valve job done. Also has a xr281 comp cam, with pac 1518's and 7.350 push rods.
All grounds are good, I have Fuel, Spark, and compression, its firing in overlap instead of compression.
The tunes i have tried are a stock 6.0 4l80e tune with the same OS, and the tune i had in the truck when i had the 4.8 and turbo.
Also other weird thing is i have to open the passenger door to get the interior lights to shut off after i turn the key off, it used to be the drivers door.
Any ideas would help.
Thanks Dustin
EDIT- I have checked the cam, its dot to dot.
