Re: Stupid Questions.....again.

To clarify; If you have the VATS and missions stuff removed but the rest left relatively stock, the same tune will have little issue running either motor...or any of the GenIII4.8-6.0 motors for that matter. The computer will use the MAF and 02's to make the minor corrections as needed. However, the "hotter" a truck is tuned, the more specific certain parts of the tune become in regards to timing, fueling, defuel etc. Even moreso when considering things like SD tuning and forced induction. Were you to build yourself a 6.0 with some bigger heads and deck work, a new valvetrain, cam, trunion and bearing upgrades,and a fueling system to feed it...you may be unhappy with the results on that existing "hot" tune. IMO I'd rather risk running a bone stock tune on a new built motor, than running a performance tune from a different build. Either way, the tune would need to be modified for the current setup regardless of the starting and ending combination. I hope I didn't just make that as confusing as I fear I may have.
