Ford Excursion 2000
I have A lifted Excursion with 37 inch tires, cold air intake, and Magnaflow exhast.I recently put the jet performance programmer in, and saw results almost instantly. It fixed my speedometer and firmed up the shift points on the truck. It was very easy to install. I would reccommned this to anyone who is looking to put that edge onto their truck. I have yet to notice a difference in my fuel mileage but then again i have only had it for about 2 weeks now. mike from New Jersey
2005 V10 Excursion
U172. Very easy to install. Entered the 87 octane performance tune into my 2005 V10 Excursion. Unable to determine the effects sice it was just installed. Unit lacks documentation on the operations, I am not sure what each tune will do and what is involved in a custom tune. I am somewhat disappointed to learn that there is not a tune for towing for the gas engines. That was one of the reasons I bought the tuner.
