Most likely if the pinch is gone in that short of time it got some dirt in it. It will last running it at 270 no problem. I have seen Go's hit 350 and not need a pinch or anything after that. Make sure your temp gun is accuarate, as long as it's smoking it's fine.
If you need the sleeve pinched just pm me.
