I don't know if anyone else with the xsr has the FTecu bench flashing kit, but I just saw this today. Graves put the flash file for their full exhaust in the file manager. Looks like it was just added last week. I have the Akro carbon full exhuast, but haven't adjusted the fuel map at all so I'm going to try this file tonight and see how it runs. I'll report back if there's any interest.
