I was most impressed by how fast it tunes your vehicle and goes back to stock in a matter of 4 minutes I mainly purchased it to eliminate my DOD it works I used the 91 octane tune and removed my speed limiter I tried both firm and hard shift mode which makes a big difference but I use normal shift because there are stories about my transmissions reliability my gas mileage is crappy with or without DOD it always says avg milage is 18.9
not thrilled to death

I bought the tuner for my 08 impala ss I set it o make the performance setting and changed rev limiter and each of the gears I added 500 rpm my transmision has been acting up a little bit but it has not thrown any codes out so idk. It may also have to do with the muffler delete system I put in place of original exhaust. Noone else seemed to have any problems cutting out the stock pipes though.
