"It was fairly easy to install. The only thing my customer does not like is that fact that everytime he was to change something in the tuning he has to take a lot of fuses out and unplug onstar it a pain when your in a hurry. Over all it helped the way the tranny shifts which was the biggest reason for buying it. As far as power goes it may have helped some but it was not as much as we had hoped." —Timothy A from Johnson City, TN bought a Hypertech Max Energy Programmer for a 2004 Ford Expedition, 5.3L V8.
"Great product! Changed my truck's personality. Towed 22 foot trialer Phoenix, AZ to Templeton, CA and back no problem." —Donald W from Phoenix, AZ bought a Superchips Flashpaq Tuner for a 2004 Ford Expedition.
"over all i like it. not real happy the fact that the speed limiter and rev limiter are all preset but i guess i can get over it. It really helped smoothed out the shift and made them more crisp just like i like the the wife thinks it shifts to hard but she will get over it. MPG went from 16 around town to 18.3 we have not had it on the highway yet. towning it made a big inprovement.with an air aid throttle spacer and k&n intake made mpg just from 18.3 to 19.89 so over all really happy" —Timothy A from Johnson City, TN bought a Superchips Flashpaq Tuner for a 2004 Ford Expedition, 5.4L V8.
