I don't have datamaster. I have a wideband that I am watching, and pulling random plugs. It was showing lean, and when I pulled the plugs they were white. I adjusted the numbers up by .5 then it was showing rich. I moved them back down to where I had them and it was still rich. This is why I am going to try new O2's.

My cam is the Comp 266, which is basically a stock replacement. I will have the get the harness to do a scan. That is next on my list.

If this ends up not working. My back up plan is to install the FMU that came in the kit with the Procharger.

Comp XFR 266? That's a long way from stock and even more aggressive than my cam, you'll definitely be gettng cam reversion (causes splits). In my opinion you'll be chasing your tail at idle with only the wideband. Suggest getting the ALDL cable (Moates does an excellent cable that converts to USB) and datamaster for 20 free scans. Drive the car around a bit, find out what it's doing above idle.

I'm not sure the FMU will help (unless it allows you to adjust base fuel pressure with an adjustment screw) - usually used only to help boost FP when the engine is in boost.
