Hey guys, my tow rig (and DD until I get the 4.6 stroker finished) is a 2003 Chevy 1500HD 4x4 with the 6.0L. I love the truck but like most people, I want more power. Right now I have a K&N cold air kit, and the stock exhaust with a Magnaflow dual in single out muffler. Im interersted mainly in a little more power for towing so its not downshifting on every slight grade I come to. I also want to firm up the shifts a little bit, the shifts from the 4L80E just dont feel like a HD tranny should to me. I'm pretty much split between the Superchips Cortex and the Diablosport Predator. Does anyone have experience with either of these and some feedback?
