Is there an update to this issue 4000 RPM dip?
Hehe.....You will find mixed reviews on this. Some say the updated software fixes it. Some say it doesn't. I know when Jim Conforti installed the Shark on my ECU and updated to latest BMW software...it did not fix the dip.
Many......myself included....are leaning toward the DISA vlave as being the issue with the dip.

It seems like this topic has been beaten over the head for years. Isn't the 4K dip mechanical and to do with the VANOS switching over? I've still never seen or felt the dip from any car.....is it in your minds? LOL

No....I don't think it's vanos related. If you've read that...please provide the link. Thanks

I have a very definite dip at 3500 rpm at load - EVERY DAY! My commute has a merge on the interstate where I am at the bottom of the hill - as I accelerate up the hill under load to merge - I get a dip at 3500 EVERY DAY. New plugs, gas filters, other maintenance done. I would love to have an affordable fix.
