I had that exact same problem on my 04 330i and I took it in yesterday to the dealership and had a DME update. It completely fixed the lag problem at the 2-3k mark. Cost me $150, car runs like a dream now.

i have a 2000 323i.
when im driving the car hard, full throttle, ill notice that my power seems to "pulsate" at times..almost like its not very constant. its not extremely noticable but can be noticed enough. its not a fast pulsing of power, just slightly at around 2500-3000rpms and again around seems like the power dips just a little then comes back. kind of odd.

has anyone else experienced this? i have no codes or anything. but after a while it has bothered me. im completely stumped.
any suggestions would be helpful. thank you.
