I have a RB Killer 9 and not sure if it's normal for it to idle the way it does. The engine starts and runs fine. Cold or warm, as soon as I let off the throttle it takes a full 2 seconds before it the rpms drop to a normal idle. To clarify, the rpm's drop immediately from full throttle to a high idle, and then they drop to a normal idle. During that transition from full throttle to high idle to normal idle it will at times push the car while turning, because it slightly engages the clutch. Any ideas?

Just had a look at the engine tuning bible and this very issue is on the front page...I guess I could have looked at that before posting. Will try what it mentioned there and see what happens.
