Default Cold Start Idle run-up?

Evern since I installed a ported FAST-92 intake, and a 90mm Lingenfelter TB, my car runs up to about 2100 RPM on a cold start. Here is a video I took this morning of it:

What can be tuned to correct this?

Mine stays at about 1600rpms, it doesn t go up to 2100rpms, but it floats at 1400-1600rpms at idle for 10 seconds or so(at least) and then it will usually settle at 1000. (origionally)When i had it tuned it idled at 900 or so but I found a vacuum leak, fixed the leak, and now it idles like sh$#! I guess it needs tuned again, huh....
