Well I finally got a chip for my truck about 2 weeks ago. I got the bully dog chip, the guy programed it for me to have 4 different settings, the first is +50 hp, next is +75hp, next is +100 hp and the last is +110 hp since I had it installed I have noticed a increase in gas milage and not to mention it will blow the rear tires off the truck now. So thanks for evrybodies help.
