Are you talking about at cruising rpm? Like around 3-4000? I may have to do that next time I go dyno.
Now, as far as disconnecting mine, I got my bike out today, started it up, choke out, disconnected the TPS, immediately sounded better at full choke idle. Got warm, rode down the street, wait for a red light, seems good, start moving again, there was a tiny lug in acceleration before right off the line, that's now gone. No popping when decelerating. This was 2-up, I'm riding tonight solo so I will see if there is much difference, but it almost feels like the roll-on power was a little less than usual. Of course, 2-up is going to feel different than how I normally ride, so riding later will give me a little more info. So far, nothing bad, so I'm going to leave it off for a while as long as it still pulls strong throughout the range. I'm with Staffo also on less parts left to break means less parts breaking.
