I also did some tuning on the dyno as well but found it much easier to do it myself on the road with Chris's awesome little tool. I also installed a vacuum gauge. Not necessary but very very helpful. And super cheap.
Yes, the vacuum gauge is very helpful to understanding what driving conditions constitute "part load," in particular. For example, light cruising on a flat road is NOT part load.
Based on my individual experiences, Anders' numbers were actually too rich for me for whatever reason.
You need to use all the "clues" to get to where you want to be, and Anders' numbers are a guide (the slope of the curve is useful). That unmolested MPS you picked up is very useful for calibrating your specific meter, but you still need to use: AFR readings, vacuum readings, performance/behavior from idle to WOT, head temps, exhaust smell, plug color, etc. etc.
