Welcome to the neighborhood! I bet you'll get many questions over here!!
I'll start:
1. can you remove the limiter?
2. Can you enable 3 way ESP on a 300c built with the new hardware (after 31 Jul) ?
3. can you change torque management?
I'll look at the "other" forum to see what you've done so far.
Thanks for posting on this side of the aisle!
