Default Low RPM at idle

After your car has been fully warmed up what rpm does it idle at in neutral?
My car idle's a little below 500 rpm. Is that normal? Should I be concerned?
I'm running Cobb AP stage 2 (protuned) with a Perrin UP and TXS Stealthback exhaust system.

Probably another case of reading the Tachometer wrong. The first tick right next to Zero is 500rpm. The tick that you are reading "500" at is really 750. IIRC Idle speed is 650 +/- 100. So you are idling ok.
