    Rev-Hang is the most annoying thing in a sports car. You guys complained about it in the Civic Si you had as well. You might need an aftermarket calibration to get that response you are looking for.

    With all the various settings and adjustments on the Vette there isn't any "sport mode" or something that will adjust this? I understand it's for emissions but don't emissions tests not usually test sport/race modes?

    my sister's 2007 sti does this also. it's disconcerting. feels like the car is still accelerating with my foot off the throttle. at the track i had to let off the pedal a second or two before my actual braking point.

    My NC Miata also jumps into full engine braking at the slightest hint of throttle lift. The engine braking in that car is rather strong too. Just flicking the cruise control speed toggle once to scrub 2 mph from the set speed induces a head-jolting deceleration.

    @stovt001 Miatas tend to have cruising RPMs almost twice that of the Vette, so it might be a symptom of engine speed.

    I agree with the others that in a sports car the lag would annoy me during spirited driving, and that I would think sport setting w

    What I find interesting about the ST Focus is that the revs hang too, but they drop a few hundred rpm first so they're almost right where they need to be for the next higher gear. I'd wager that the rev hanging in this Corvette would be more tolerable if GM had calibrated the motor similarly.

    I'm not completely satisfied with the explanation. How long could it possibly take for the cylinders to "clear" with the injectors shut off? At 2000 rpm, the engine is spinning 33 times/second. That's 16+ full cycles per second. That, and there's plenty of friction to slow the assembly down throttle plate opened or closed. Shut an engine down (one with a mechanical throttle) the second you floor it and see how long the revs hang... They must be ramping the injectors down, maybe to reduce NOx (?).
