DKM , the list you summarized is exactly what i am experiencing. i would say it definitely revs higher , but with less power top end. I am working with a couple of guys to try and resolve this; one is a computer programming "master" and the next guy specializes in ECU tuing. If they cannot crack it i don't think it can be resolved without changing the ECU.

2nd...the shift point seems higher then before. It now spins up to 68-6900rpms in 2nd and 3rd. I actually ran into the rev limiter when i was driving the dog piss out of it.
3rd...the car is very soft out of the hole. It used to be really jerky with 1/4 throttle take offs. Not so much anymore.
4th...Mid range and upper end HP and torque is soft. It really feels like 2-3 degrees or maybe more have been pulled throughout the RPM range.
5th...During 4th to 2nd gear kick downs is softened, its not as violent and its not as rapid.
Overall..i think 2003 and 2004 PRE FLASHED Ecu car will stomp a mudhole in 2005 and 2006. The reason I say this is because my friend that helped me find this car, and used to be on this forum until he traded in his 2005 E55 for a different car, I drove his 2005 many times before I bought mine and his always felt soft. His car was fast..but it didn't have the "hard edge" mine DID.
I don't know...maybe I'll do the Kleemann K4 upgrade sooner than I thought.
later,
dave
