Damn your just gonna jack my thread like that huh???!!!!

lol, no harm meant... u can remove the post if u wanna..I'll add it to my sig

naa just giving you crap dude its all good

Good.. I'm asking more than you anyhow..maybe yours will sell quicker!

i was thinkin about gettin one of those. what exactly can i do with it, how much more horsepower will i get, etc....all the goodies. i have a '04 4.8.

You can of course, program for more power, change shift points, change the rev limiter, change the top speed limiter, change for different gear/tire sizes, alter the shift firmness... I've heard they can add UP to 18 HP, but I'm not sure.. I know I can tell a difference when it's not installed.
