- Though we turned off DSC the car kept turning it back on and diverting all power to the rear wheels
- When trying to run in 6th(even with the level held back to keep it in 6th constantly) the transmission would bog down and also turn traction control on for all 4 wheels.
- When full throttling anywhere below 2,200 rpms on the dyno would also turn traction control back on for all 4 wheels.

The only thing that worked was starting the runs at 2,200 rpms in 4th and the car only allowed the rear wheels to spin. Even then, it took us several tries to get clean runs.

Again, I will analyze the numbers for the other two settings and post the results. I will also consolidate all this information to my original post.
To turn off DSC completely though, you have to HOLD it longer. Is that what you did? Just curious, and thank you again for all the money you spent on doing these tests for us. I greatly appreciate it, and I am really happy knowing that my base settings are at 507hp so my car is in fact around 514hp in the C setting.
