I have a question I would like to ask...
I'm currently supercharged at 11psi, and everytime when I go wide open throttle and then come to a full stop at idle, the rev will bounce up and down between 1000rpm to 2000rpm continously.

I can get it to go away by either driving it off or shutting the car off... does anybody know why it's doing this and how to fix it?
I tried the idle slider (to the left), the further left I go, the more it helps the situation (I think it acutally went away); however, the further left if goes, it also causes the idle to dip when coming to a stop under cruise or from WOT and stalls the car.

btw, i checked all bolts and nipples and there is no vaccum leak

Adjust your TPS so that it reads 0%. Flatten the cam angle tables just above idle and also reduce the ignition timing.

Remember that also a vacuum leak or stuck idle valve can cause this problem - and both are fairly common occurances.

It's funny, because this only happens at idle after I put the car under WOT. If it's normal driving it wouldn't do this.

Also, I also got a question regarding to the idle.
At idle (set at 900rpm), the car will dip into 830-840rom for a quick second and you can feel the car hesitate for a bit and come back to 900rpm.

When i did a datalog, everything is fine... but as the rpm dips, ignition jumps up to 10... when it gets back to 900rpm, the ignition value goes varies back to 1-4

I found this in one of the reply's HONDATA gave in a misfiring thread at idle:

Welcome to Honda's ignition controlled idle speed. -2 to 10 degrees ignition timing is normal at idle - the main table is not used.

so that means it's normal for ignition to jump to 10 at random and rpm will dip 40rpms or so and hestitate?
