Corey G from Pensacola, FL said, "when i was shopping for a upgrade for my truck i seen this one and the reviews looked good and so did the discription, however i was under the impression that it was a actual programmer to where you could,say for instance change your tps. it does not, all it lets you do is display all the majr components of whats happening under your hood. its nice it diddnt give me the power i thought it was going to, i called jet force and the guy said it really only gave me about 8 hp, how ever the fuel economy went up iv been driving for a week and a half and still stitting on above 1/4 tank, normally i fill up everyfriday in my tundra. so it was worth the money in the fuel savings, next on my list will be the volant cool air intake,maybe that will help a little more"
