I am pulling my 6.0 out of my 01 Silverado and replacing it with a mild built 416 cu.in. motor. I have read that I will need to update the cylinder volume in my tune to match the new engine. What parameters, if any does that change? What happens if I leave it on the factory 6.0 setting? My truck was originally a 5.3, but was swapped out for the 6.0. The tune still shows it having a 5.3 cylinder volume. So that?s why I was wondering do I really need to change it. Can?t seamto find the answer.
