For a long time, a few guys on here and myself have been working on figuring out how to code off the electronic nannies that these cars have. Even with DTC an DSC off, there are still tons of safety systems in place - many of which I was not aware of until I started doing research.
Now that I have coded all of them off in my car, I thought it would be useful to compile the information into one place. This would have really helped me when I was trying to figure it all out. Things I have actually disabled and tested myself on the race track:
Electronic Differential
Engine Power Reduction to Prevent Brake Disc Overheating
Brake Fading Compensation
Hydraulic Brake Assist
Maximum Brake Support
Brake Standby
Dynamic Performance Control
Some of these are interfering everyday during normal driving, such as hydraulic brake assist. I didn't even notice it until I turned it off and had an "Eureka" moment.
All of these things suck for track use and spirited driving. Some of these will not be new to you, but at least it is all written down for easy reference in one place with results of me actually testing the coding on track.

Hope it helps!
