I think I'd rather have the updated DISA, which is what BMW was replacing per the initial SIB.
I was doing some more research on this as my car was reprogrammed and the dip has come back. It is still pretty bad. When my car hits 4k rpm you feel it die off bad and then when you hit 5k rpm you feel it pick up hard again. The ONLY time it doesn't do it is when the car is just warming up in the morning. Since your fuel curve is fatter during warm up this means the 4k rpm dip is coming from a LEAN condition in the engine.
To make matters worse I had a friend of mine at BMW order me the newest DISA to try it out. It improved everything significantly, but didn't eliminate it. For the $200 I decided to try other things before keeping it. Talk about annoying. My friend has an 01 330ci and it has no dip to speak of, why is my "special" car damned to this inferior performance?
