I test drove a L5P last Sunday and put my foot in it a bit. Itwas impressive especially considering it was stock. It was a dually, like my LMM. I have the Banks Monster exhaust, Ram air intake, and Economind tuner, which is not a race tune but has pretty good balls in the upper levels. The L5P would definitely hang with the lower to mid tunes in my opinion. But, oh, the creature comforts....

Gale Banks put an L5P on the dyno and told his guys to run the engine until they killed it. The dyno died before the engine (snicker)
