i know the 2 have very different componets but i was wondering what would happen if i try to load a lb7 or lbz tune on an lly, would it work or are the engine values completely different. if i cannot load a tune to an lly can i use the same parameters from a lb7 or lbz to change a lly, i'm new to this and cannot find a good lly tune or anyone to help me out. any help is greatly appericated.
