Forget it. Other than being light on the throttle, I haven't seen any proof that anything here will improve mileage. I have the BullyDog tuner and although useful for power, it does nothing for fuel mileage.
I bought it for one reason only. To get rid of the WOT restriction. That is does. If it does anything more, I haven't noticed it.To this day, I'm still shocked you bought a tuner.![]()
