As I am new to the diesel world and looking to buy a duramax truck, I read the specs and see only small differences between the two. I do not see any big differences in the LLY & LBZ. Is major performance difference that the LBZ has been tuned different coming from the factory? If this is true, then theoretically, the LLY could be tuned to basically the same output as the LBZ. If you install an aftermarket tuner, then you should basically get the same output? Any thoughts for a soon to be newbie.
