After some more research, I decided to go ahead with the Noelle tune. They basically reprogram the entire computer. Took almost 2 hours. I have had several tuned cars and this thing is really stout. Shocking actually.
They are in Germany and my local shop connected to them for the download.
Here is the info from their website:

I had heard that they do the software for BMW software?
Warranty is impressive
