Does anyone notice that when you rev our engines (like when you want to sound cool when downshifting)that it seems to take (forever) a long time for the engine to lose R's and come back down..like sometimes 3 or more seconds..what up wit dat and is there a cure or is it just my car? Or could that be the bain of efi vs good old carburetion?

They all do this with a stock chip. Aftermarket chips, they don't.

Several theories why, including smog restrictions, maintaining electrical current to the anti-lock brakes, etc.

Nothing to worry about.

The feds came out with emission regs back in '72 that required less pollution at an idle. The autos then developed a retarder to slow down the deceleration to idle, thus reducing the amount of "whatever" pollutants that were being emitted. I believe the timing is also retarded until acceleration.
