I was pumping gas and this guy in a Avalanche rolls up compliments my ride and shows me this little box he says he plugs in and it reprograms the car and he said he was getting close to 24 MPG with 30 inch tires and such because of that thing. I was in a hurry and had alot more on my mind. Now come to think of it a month later. Im sure alot of you know about these things. Any Help Appreciated

Avalanche may get 24 mpg on the highway, I got 21.1 coming back from Montana thru North Dakota. I have the Preditor programmer, but there is no way he would be getting 24 mpg with 30's, just not happening because the wheels and tires would take away too much mileage. :)
