what gearing do you have in your truck? you can get lower gears to help the power at low rpm's to get the whole load moving.. also, what wheel setup do you have, I got rid of my stock 20's for stock 17's for a lighter setup. Can also look into a cai and a catback setup to improve engine performance...after that there is not much else you can do until one of the tuning mfg's has deciphered the pcm and make an aftermarket programmer for the new years..
