predator file for 09+ 5.7L - should it be different?

[pbgear]

with all of the engine changes (some say it is a completely different engine) for the '09+ 5.7L engines it seems as if a unique programming table would be beneficial for this motor - instead of using the same tune files from the pre '09's.

does this make sense, or am I wrong?

the reason I ask is that according to the evic my 0-60 times are slightly slower with the predator tune than with the stock tune. I also saw another recent thread here where on a 2009 a guy dynoed the stock tune vs the the predator tune and actually lost 3hp on the dyno with the predator tune.

The Predator knows exactly what year the vehicle is and applies the correct tune in all cases, it is not a generic 5.7 tune by any means.
