Default Idle Sticks at 2000rpm

Just wondering if somebody can point me in the direction of how to fix this. I have read on other boards that it is part of the decay tables in HPTuners, but how much reduction is too much? And is this even the right thing to do?

Car is a 2002 Z28 A4, with LG5-X3 cam, A4 with stock converter (yank ss 4000 should be here next week), Hooker supercomps headers, and SLP lid. it seems to do it most of the time, especially when just at a constant speed. I think that's why it causing a TPS insufficient activity code as well.

so it only does it while you are cruising in drive? What happens if you rev the engine in P/N? Do the rpms come back dow quickly, or hang for a while?
