Guys I am saving up money for a wideband 02 sensor. Until then I've done some tinkering with my buddies '04 6.0 liter 2500HD. Of course the first thing we will look at after re-writing the PCM with my guesswork is if the truck drives normal and smooth. Assuming there are no hickups, what should I monitor, and how do I set up the Flashscan / Scan tool so that I can monitor this data while he's driving? (hehe, I hope I didn't "tune" his tranny too much).
Thanks.
