not with those tires. my buddies power stroke went from i think 15 to 21 with a good chip, but he has stock tires, and that was when he could keep the right foot out of it.
Im getting a average of 21.6 MPG on the freeway and 15.6 in town driving.
Thats driving normally. when I drive a little faster it drops about 3 MPG respectively on both figures.Truck is completely stock down to the tires. Funny thing is on the street this truck gets better gas mileage than my dodge did on the freeway
I went from 13mpg to 16mpg after putting in my chip. Milage is the same in 80e or 120race:dunno:, but the 80e is much easier to run in town.
