"Just bought it to improve my Transmission Shift changes when towing, or alone w/ my Family..( Ford Expedition V8 4.6L )
Just 30 secs. after i installed the Performance program immediately worked better and smoother, I had already a PIFK k&N High Flow Air Filter system and a Throttle Body spacer.
Modifying the Computer was the best think i could do..Now Runs better more power and Saved a lot of Gas, i made a more efficient Engine..My best investment for this Truck...." —Luis F S from El Paso, TX bought a Jet Performance Programmer for a 1998 Ford Expedition, 4.6L V8, EFI, automatic transmision.
