I bought an engine for my Trans am and got the tune file with it.
I am swapping LS1 for LS1, the new engine is cammed.
The cars are the same as in both manual and both 4.11 rear.
My question is does the VIN need to be changed on the file I received? Also would VATS be an issue?
Or would it be easier to answer with the steps I need to complete, first backup my current tune, step 2, etc...
