One of my customers bought a truck with this tune already loaded in.
I pulled it to take a look, and wow, that?s a bunch of timing
truck starts, runs, drives, and has been like this for some time.
I have not data logged or done anything to it, as it?s in the shop getting body work, but i have to guess its pulling timing everywhere
This is a lifted vehicle with 40-inch tires, 5:50 ring and pinion, stock convertor, 5.3, truck norris NSR cam, short headers, no cats, 4" single exhaust =, that's it, nothing special.
Any ideas why theyd crank the timing and VE like this?
