Older M5's have electronic throttles that can actually be adjusted for sport mode if Im not mistaken. I suppose Subaru programmed the delay in (and made it less sensitive) to avoid people spinning and the like.
I don't have the link, but one of the ECU product vendors (I believe it was an ECUTEK vendor) stated that part of their remapping was in fact changing the mapping of the throttle by wire. I agree that this engine has a relatively sluggish response to throttle "blips", which I had previously associated with a heavy flywheel effect.

I have to keep telling myself that this isn't the old days!
