an 06 z51 and a 07 z51, both mn6 both bone stock, now they are normally neck and neck... until 06 downloads the performance tune frome a diablo sport II , now the 07 is always ahead by a car"s length sometimes 2 , 07 puts on a snake charmer intake... the gap is wider, took off the cats put on straight through pipes ... the gap is even wider.... that's all normal... now here is when the mystery begins, 06 bolts on the same CAI and bullits cat backs....and we're back to square one.... 07 is always 1 car length up.
now my question is how the F*** is that happening?
does eleminating the cats do that much? is the tune hurting my hp? shouldn't i be having the superior performer package? or is there a fourth dimension of vette performance that i'm not yet grasping?
(bare in mind 07 is getting 377whp with only CAI and no catalyctic converters on 98 octane gas)
