Ownage, your performance level is Level 13!

The highest functional value on P35 is level 12.

It seems that P965 can go even higher (looser).

If your performance level is not displayed it means that it is out of the range.

Changing it will work just fine since there is nothing wrong with the programming.
You can start by setting it to level 12 and lower it from there.

Huge boost in performance incoming
