I installed the unichip because of the mileage/performance gains that I had read on here from another user (tacorock). It's a piggy-back system to the ucm that changes the air/fuel as well as the shift points. I was able to bump up the mileage from 17 to 20.5 with the change alone. I could also tell that it did shift better at hard accelleration. I know that in order to really set the maps correctly, it needs to go on the dyno and have it tweaked in. I haven't done that.
Also, I know I'm asking for throttle response but I also put about 650 miles a week on my pickup and can't afford to lose the mileage I've gained by yanking it completely. Are you guys seeing any mpg changes out of the urd
maf calibrator or just the tunability to really tweak it up for performance? I really do appreciate the input.
