I have HKS 264 in my car an i idle between 900-1100rpm. Your is a little high but not to bad. Did you try to adjust the idel screw on the IAVC. Let the car warm up and turn the screw on the IACV thats between the 2nd and 3rd intake runner i think, on top of the IACV.

If this doen't do any anything the you can clean the IACV or just try and seafoam the car.

Funny i almost have the same setup. What boost do you run and what kinda of power are you making?

My tuner told me that all sr20s with aftermarket cams idle better at around 1000-1200 rpms do not know why??? It might die if it was only to idle around 800 rpm all the time?
