Is this a problem or normal?

I have noticed recently that when I come to a stop after a quick acceleration my RPM will come down and stay at around 1500 RPM after i press the clutch down. I would sometimes have to blip the throttle to get the RPM to come down to the normal idle. Is this normal? Is my Idle control valve going bad? Keep in mind my car is supercharged with the G-Power kit and I know there is a reducer that is used at the rear of the plenum going to the Idle control valve hose. I also got a few codes that came up when I had a local coder code my car a few weeks back. I am not sure if these relate to idling issue or not. Any help, comments, or suggestions would be appreciated.

Here are the codes.
