Is it a transmission issue?

I know there's been a lot of to-do around this engine's lack of turbo lag, but realistically, it cannot be eliminated, at lower revs especially. No matter what patch or update is applied.

My E53 was a twin-turbo 30d. At low range you could hear the whistle of the air being sucked in as the engine picked up power.

I do take your point that there will be some lag from the turbo. That being said, I did notice that the lag pretty much disappears in Sport mode as the engine runs a bit faster and gear box tends to change in a very narrow range between 1500-2200 revs. The car, when pushed, feels like a motor bike changing gears rapidly.

All in all, it is not a major drama and sport mode driving solves the issue. I had just wondered what the difference really are between normal drive mode and sport mode. The car is clearly very capable to not have any lag at all and I was wondering if there was a easy tweak to remove it as it just seems like some kind config in one of the ECUs.

In the grand scheme of things, this car is awesome.
