Performance Tuning
Does anyone know if it is possible to modify the PCM on the 4.0L?
I drive a '96 and it is OBDII. I'm not looking for any of the performance chip stuff, I want to be able to either use a programmer or plug it into my computer or something.
Thanks in advance.

LOL it would be cool to have but my 4.0L is bone stock except for the new Flowmaster I put on in the fall. I don't feel like blowing it up when I only have 72k racked up on the odometer.....
My main goal for programming is to raise my fuel economy and lower the shift points a little.
