When I throttle back on my otherwise smooth running 13b turbo, I tend to get a bobble (miss?) as the engine spins down.  I don't seem to have it if I throttle back very slowly and smoothly, but fast moderate (usual manner) or quick throttle back produces it.  I have noticed this on Lycoming's if throttled back quickly, but obviously not an issue that I have noted in a regular car engine. 

Just curious if others have had this occur and if so why.

The list has been especially quite lately so come on folks, here your chance to shine before I start calling DAR's ;-)
