I'm using a JMS chip in my 'Stang. I had lost power and mileage 'cause I had put in a few intake mods; I was running on the edge of lean, and the computer couldn't compensate. I had even bought an adjustable fuel pressure regulator to richen the mix, but that just made my mpg worse. The chip mainly redid the air/fuel curve in the computer, which has me running a more efficient mix.

If I baby the car for the entire tank, I can actually hit 20mpg. I've done it once or twice. Was hard to do - I am such a speed junkie.

If you want better gas mileage, make sure you've worked out all the bugs in your 'stang before you try a chip. No chip can help if your engine isn't running as smooth as it can.
