RE: 5.7 V8 vs. 5.3 V8
well to end the question!!
a guy at works son has a 97 350 vortec with 3.73 gears reg cab vs my 06 5.3 3.42 gears ext cab. he has an intake and exhaust so i unprgrammed the hypertech and we lined them up.
we did a couple of "fake runs" for both of us to get use to it then did 3 back to back off the line runs on 460. and the winner was the 06!!!!
the 350 did a pretty good job but once my truck hit its sweet spot above 4500rpm it rolled his. then my buddy with the hemi ram blew past both of us[:@].
go the hypertech sold on ebay so now i have to decide whether to pay a credit card or call Neslon performance and get one of their 87/89 dual tunes.
everyone have a great memorial day weekend
