DSC is:

Don't turn off DSC if you're not ready.
Set verocity to level 5.

If you still feel it's "lagging", then you must have switched gears below 4000 RPM.
Try switching it at 4000 RPM, it should solve your question.

Keep us posted!

Do you have the the most recent software for the SMG? If so try the reset other wise the gear position sensor may be on its way out, you'll know this if it starts to skip gears. Like 2-5.

Chances are you're experiencing normal operation of the SMG system. On my car, when shifting from 1st to 2nd at low RPMs (below 4000) I have to count "one thousand one one thousand two" before it has completed the gear change. At higher RPMs it completes the shift much faster.

If you think about it, and if you have driven a manual transmission car before, when you're simply tooling around town in traffic, you don't normally quick shift from 1st to 2nd anyway, so the SMG doesn't realy behave much differently then you would driving a manual trans yourself.

^^^ This

Mine does the same. great info and answer. Sounds like normal operation to me also. It does take a bit of getting used to when you first drive the SMG.

Most likely it's just not knowing how to drive the SMG car. If, for example, you're at level 3, and you're shifting @ 2.5k rpm AND you're lifting off the throttle.... it will shift very slow.

Suggestion: use level 4 (never anything less), shift a bit higher (like 3.5k rpm) and don't completely lift off the gas (just lift a little) and you'll be MUCH happier.

Either that or get a stick shift.... Ha!

Nothing wrong with that.
But switching it at 3K, when you're at level 5, seems like you're trying to bump up MPG.
