I noticed the engine opens up now when I want it to. Before the response wasn't there. But it wasn't easy figuring out the shifting configurations. I had to research some forums but there's not much shared about it. I paid $275. Great deal

before i purchased i read the reveiws of all the tuners i could find for my truck. this one seemed to be the one for me. it works. however i havent noticed much of an MPG increase. which is why i bought the tuner. maybe if i could keep mt foot out of it, it will work better.
