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?
Nelson tune.

The superchips still runs the a/f ratio on the conservative side, so chances are the 6L will have enough fuel; just be sure to get a wideband on the truck before going wot to ensure the a/f ratio is rich enough.
Both engines can accept about the same amount of timing, so it shouldn't ping.
The only way to ensure the engine is safe, is to have a scanner available so you can monitor the engine.
