The idle will increase as you pull out the fuel shut off, this is normal. Think of it at starving it for fuel a bit to build temp (bascially like a lean out for a carb in a sense) You MUST only be at full fuel from the burnout book to the turn off at the end of the track, it puts to much fuel in at idle if not and this is most of your issue I am sure.
There can be a fine line sometimes on in to far and out to far, 2200 isnt bad and might be a good spot for it, you'll know as it will die if its out to far.
The wrist band deal does work, many people use this for a band-aid fix for the issue. The moroso canister to get is No. 85467
You can run a high speed to fix the 1 pump, but its all a pressure deal and a 0 1/2 would be a quick fix, maybe call Enderle and see if they can re-size it ?
Let me know if I can help you with the injection any further.
