I am doing some speculating here, but I believe if you put the standard LS3 cam/lifters in the L99 you could gain back the 22hp, and most likely safely move the rpm limit up to 6600-the same as the LS3. May as well do this if you are going to tune out the AFM mode anyway. With the more aggressive gearing of the auto car this would be one nice mod. Of course, economy would suffer but oh well. The only thing I am not sure about in terms of raising the rpm limit is the VVT setup, but I don't see why that would hurt, I think the timing is most likely fixed above a certain rpm/load anyway.
