I noticed there were various levels of sound from the Supercharger. No load = No Sound, Moderate Load = Just getting started Sound, High Load = Deep Growl Get out of the way sound.
I also tested a quick merge onto the freeway. Could only get part way into the throttle as 35 to 75 was just so quick I overshot 75 and had to hit the brakes.
I did some 4wheeling on snow packed forrest service roads. No issues noted. The Supercharger did not engage at any time and the engine was its normal predictable self.
MPG is now at 20.2 as I has some highway time. Most of my MPG hit comes from the first 2 miles of driving. The Ultra Gauge indicates most of my driving is done Closed Loop, Very little boost or a little vacuum and timing advance 25-30 deg.

Awesome! Looking forward to some accel and sound videos!
I've never used Ultra Gauge, but 23 lbs boost? That must be reading in absolute pressure, right? Assuming sea level atmospheric pressure, 23 psi would be 15 psi atmosphere + 8 psi boost?
