Just annoying. Put in a K&N filter and it'll drop a little quicker. At least it did in my 96 GTS. Not much but a little bit quicker drop.

Although it is just hearsay, I have heard the same thing you did. The computer keeps the revs from dropping quickly so that the engine can burn off unburned fuel that remains in the port from high rev-WOT application. Supposedly it reduces emissions. I don't mind it, and haven't come across the bucking that porkster experienced. If anything, it keeps the motor from bogging between shifts. Might be a clutch adjustment in your future?
