It's not that bad of a chip. I was getting 11 mpg and now I'm getting about 16 but I'm also running premium gas now so....there isn't that much difference horsepower wise either. I'd probably go with a different brand if I was buying another one

Got this for my 2003 Duramax and am well pleased. Haven't really played with it yet, but had one in an 05 F250 that was scary when turned all the way up. Usually use stage 2 for everything, but do kick it up to Stage 3 when on a trip on the interstate.. Stage 3 is too much for around town every day driving.
