Ah, the never ending quest for more horsepower/torque, cubic inches, lower ET's and on and on, an illness many of us suffer from. Since Heatwave appears to have a severe case, may I offer this prescription:
Since you plan on doing your own tuning, TTS Mastertune with it's V-Tune and DataMaster features will provide all the data and tweaking you could possibility want.
As stated by "mcflyer" and others, Dyno numbers can be all over the place because there are so many variables that can impact the results. Plus, dyno time is expensive.
Since your goal of more HP/TQ really means "I want go faster", install a on board performance meter to actually measure your 0-60, 0-100 times, 1/4 mile elapsed time and mph, flywheel and rear wheel hp, and measure this real time while driving your SEUC. PerformanceBox from VBOX USA is a GPS based meter and will work well on a motorcycle. This will make the "seat of your pants testing obsolete. The cost of two dyno runs will more than pay for it.
