OldMoparMan63 will become famous soon enough


I didn't notice any difference with/without it.

I lie...... If you run the 91 octane program, and run a lesser octane, the truck will ping, so timing HAS to be advanced with that program. I just didn;t feel it if it was, nor saw any gains in anything, including horsepower.

I kept the unit to use it as a scanner to obtain codes if necessary.
