wow! that's cool... saw the car at SEMA and it is a great "sleeper" in that just looking at it I would never guess 7s.
It sounds like you are using the 6spd as a 4spd (I only hear 3 shifts/4 gears on the vids) which is fine... but at first I thought you were actually going to be shifting six gears in ~8 seconds which would be nuts

Or am I hearing that wrong?
