I was talking to Mean05 about a 5.3 to a 6.0 swap in my 03 z71. I have a superchips flashpac tune on it now with a K&N airbox and duals. Means tells me that the timing in the 5.3 ecm might be to advanced for the 6.0 and could cause detonation if not correction. I have talked to superchips and they are able to write a program that is downloadable to my tuner will this fix the problem? What do you folks suggest?
