So, a little update. Just checked in with the guy who bought this transmission. His response below. (Cleaned up some language, but otherwise verbatim)

(1/3) That tranny is .... absolutely fvcking impressive!!! I'm only running 9lbs right now because I'm waiting for my tune guy to dial everything in before I (2/3) turn it up. Driving normally the shifts are nice and barely noticeable. Medium throttle they are more pronounced. I've only 3\4 throttle'd it (waiting (3/3) for the tune for full throttle), and the shifts are instant and solid!!! It adapts to how I'm driving. No hard shifts under light load and I love it!!!
