all it does is make your truck run rich so it "feels" like it has more power. Not worth a darn.

 

probly just like all the other plug and go chips out their. it will slightly change shift points and pressure, slightly adjust fuel pressure and blah blah. this company seems a little too willing to lie. they say it will not void warrenty, will give more power and will give better MPG garenteed!! i call doohicky.. just MHO...
