I have also noticed it most often in city driving, as for the most part little engine power is required after you have reached cruising speed so the conditions are idea for MDS operation.

When in MDS mode, a slight increase in throttle will usually feel like a mild shutter, and a heavy press of the throttle will be followed by a noticeable lag or bog as it changes from MDS mode back to 8 cyl mode. Once you tune your senses to feel it, it is very distinctive.
Ah, yeah I've felt something like that. But only after I had my CAI put on. I thought it might just be the engine getting used to it or whatever. I heard about unplugging the negative battery connector, but thought that might wipe the EVIC so didn't bother
