Not sure this is the root of your issue though...
You didn't say if you installed the jet's and needle that come with the AIS kit.
The first thing I would check though is that your fuel tank vent is working properly and it's not causing a vacuum in the tank starving you of fuel during harder running.

I just got my 08 WR 450 back from the dealer who installed the AIS kit. It ran great first 30-45 minutes. Then after a few open throttle runs (drag racing my friend on his DRZ 400) it started cutting out and losing power like it was starving for fuel or air. I live in Dallas,Texas so I don't think the jetting is a problem. After continually working the throttle more the loss of power goes away and then randomly happens again throughout the day. I didn't have them remove the gray wire on account of what I read is that it is just a rev limiter. My fear is that I will climbing a hill and it will start cutting out again. Does anyone have a suggestion?
Yes, take it back and make them fix it while you wait.
