I like the shift points - Gas mileage increased - haven't pulled the trailer yet - I think it will help.

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

This Cortex is great! I installed it on my 2002 F350 7.3 and could tell it shifted different and was saving me some diesel. I love it that you can download the latest program. I use it on my diesel for weekend four wheeling and then return it to stock and use it on my Mustang during the week.
