I think 1st gear and maybe 2nd upshifts prematurely and don't know why. I think that engine reaches max hp at 6200rpm anyway, so you're not really being cheated of your 360 horses.

I must try this DSC off, manual mode on the X3.

I concur. I'm not technically robbed of my horses :) however we do fall off lower in the power range as a result. Also, as you said, it seems that 1st and 2nd do that, because when I pushed 3rd I reached 6500 with no auto upshifting, I had to shut it down because I was on the highway and it wasn't the appropriate time to test out any further...

Yes it is the Dinan software. Same on my car, it wont move in manual mode unless you tell it too. I guess it could come in handy if I ever have to tow something.

Nope, this trick doesnt work on the X3. Still has a mind of its own in manual mode with DSC off.
