Everytime i drive my car and I shift to neutral when I only want the car to roll, the RPM tach needle jumps about 500 RPM's up and then down to normal. Now, is this normal? Anyone in here has this happening to them too?

Very common. Seems to happen to most of the GT-S 6speed owners.

Nothing to worry about though. Most have concluded it's just the ECU adjusting.
