The powervalve is mechanical and operates with rpm (governor throws out ball bearings and engages the PV at certain centrifugal forces). Thus, if the PV works well on the stand (can test by removing rhs cover and running the bike with the engine with it off), then it should in theory work in all gears.
So to me, your issue sounds more related to engine load. I'd be looking at either fuel or spark.
