Im trying to find a little bit more information on these. Are they as easy to install as it seems? I've done a few valvebody upgrades on various vehicles, would it be something I can do in the driveway or should a good tranny shop do it?
Will this valvebody also increase main line pressure and clutch holding power like a normal performance valvebody?

Mainline pressure will not be increased. What happens is the Transgo trim valves allow mainline pressure to flow in to the oil circuit where you only had control main pressure. Control main is knocked down mainline pressure. Not hard to do.

So would this valvebody work on an upgraded tranny for a high HP application or is it best left to the towing only crowd?

This valvebody will work fine in a high performance truck.
