My own 2 cents:
Next tuning session have him run the bike pull after pull until you get three repeatable runs. I have had maxes require 10 pulls until reach a plateau. With out doing anything else we know your machine was rich. 9.5:1 is super fat but it should also be stated that the LSU4 sensor used by the Innovate doesn't read very accurate down there. They are good from about 10.5:1 through 16:1 Have the tuner make back to back pulls regardless of AFR (except of course if it's leaner than say 14.5:1) until the power numbers no longer rise. That way when you start changing mains you will see not only the AFR change, but the power as well.
The problem with two pulls and a jet change is that if you change jets fast enough the heat soak will give a subsequent rise in HP. There's no way to tell that just the jet change gave the hp increase until a nice repeatable power level is observed. Now I say that knowing full well that a change resulting in an AFR of 12.5:1 will certainly yield better results, but the point is you might have had a 140hp combo with the previous jetting, you just don't know how much higher the machine would have risen.
Therefore, if you can get him to do it, for every jet change get three repeatable runs within 0.5 hp before moving to the next jet change. That way you have documented proof that your final AFR produces max hp.
