Default Reason for idle not decaying?

Since I put in my cam (98 camaro), whenever I come to a slow to a stop(6speed) and put it in neutral, my rpms hang at 1500rpms and do not come down to normal idle until a complete stop. I've put some idle decay using Hp tuners, do I need more. Why does the computer do this? Someone told me when you make over 400rwhp it is necessary for it to do this, is this correct and why?

I put a LS2 402 in mine (98 z28 M6) and I am having the same issue. I am currently waiting on HP Tuner myself and would like to know the answer so that I can fix it when I get it.

That is most likely the throttle cracker giving
more added airflow than you need. There are
some peculiar features to the stock table. It's
under discussion in another thread.
