Did you conect up the pcv line going to the UIM?
You can also plug up the hose going to the AWS to see if that is sticking.
One thing you might be able to do if you have no help from someone else it to lower the rev limiter in the PFC so it is a little bit safer to troubleshoot while the engine is running.

Look at the items that are bolted to the intake manifold (lower and upper) other than vacuum hoses. If you have block off plates make sure they are not leaking. There is air entering the motor some where between the throttle body and the engine. Spray soappy water around the lower intake manifold and the engine block or all around the area.

hey guys...i got it all sorted out now...like papsmagu suggested...me and phil started investigating it and couldnt figure it out
about an hour and half later of trying stuff...it turns out there was just build up where the throttle plates close...so it wasnt sealing completely shut...we took some 1500 grit sand paper and cleaned up the ports and she works like a star now
we didnt see it because it was such a small difference that we only realized that it was that after we did it lol
