I'm just giving some info at high speeds, regardless 4 wheel drive is slower at the top end. Traction doesn't have to do with anything, it only helps in the beginning. But I agree something is wrong

I understand that AWD is at a disadvantage at high speeds. I had a G37 before my last two 335i's. I ran plenty tuned 335's with my G back then. It wasn't pretty for me. No contest.

Update .....

Car had a boost leak...Charge pipe was not installed correctly.
If you heard the weird sound in the video, that was the rear engine seal.
I must say that the car feels freaking amazing now...Cant wait to do the Alpina Flash!

Thanks for the follow up and glad you got it fixed. Sounded like a boost leak!
