does any one know how the timeing is done on this truck the engine is 5.7 vortec it is MFI i have heard that the timeing is non adjustable and i have set the timeing can any one tell me how much the cumputer adjust for out of time..
i have put a fastburn 385 engine is this truck but i changed the cam to the cam that matchs the profile of the computer so that there will not be any progm issue's or engine issue's
i just need some more information from GM tech that can tell me about the problem with the timeing..
i was told that the timeing had to be right on and set to zero with the mark in the V on the timeing cover that has been done
but i was also told that i had to rev the engine to the limiter of the computer to make the computer relearn the timeing if i was off.. is this true>>>> that would mean i would have to rev the engine to 4500 rpm no load thats very bad on a engine with no load right?
please help....
