"I had got a cold air intake, JBA headers and a dual custom exhaut with a Magnaflow muffler for my 2003 v6 3.0L ranger to give it more power. But after i got the Jet chip it now drives like a sports car. Now with the chip I get about 30 miles to the galion form the 22 stock and i have gained at less a 100HP.
The chip is amazing!!" —Otis W from Tuscaloosa, AL bought a Jet Performance Module for a 2003 Ford Ranger.
"The Install was easy, the Truck seems to be a more alive, I am sure that once I add the Mass Air Flow Sensor, and headers it will really perk up." —Rodney K from Herriman, UT bought a Jet Performance Module for a 2003 Ford Ranger, Automatic, 4.0L V6.
