I just wanted to report that my car had the famous pull to the right issue. The dealer tried to align the car but it didn't work.

I had the Conti Run Flats 17"

So I recently installed my 21" Alpinas with Conti non run flats and my problem was solved. And my car rolls smooth with no vibrations. The run flats would not balance correct and would shimmy on the freeway at higher speeds. I have to say BMW made a poor choice in tires to sell these cars with. I had a radial pull which in some cases for others this may not be the issue but I thought I would share my fix which might work for some if you still have the conti run flats.

I'm going to the dealer to get software update anyway next week at no charge.

Next is the solution to the throttle delay.

I've had everything repaired minus tire replacement which I am now sure that is my problem too. I'm going non runflats next. Thanks for the post.

Lag exists even after a tune and throttle remapping. I've been told a DP helps in that area.
