    I personally like HP Tuners, I have it on my truck. It is a great program that you can really get the most out of your truck. I have a friend that has a 01 4.8 silverado single cab with hp tuners and a flowmaster and is running 14.8 at the 1/4 mile track. That's a great improvement over stock!

    I would reccommend calling justin at Blackbear performance. Of all the tuners I have dealt with the truck and other cars he was the most honest, helpful and knowledgeable. He uses EFi live which will be coming out with a handheld that he can put multipte tunes on and change them as you wish.
