From memory, no facility to cap that at 10.5. Best bet is to contact rabies and have it flashed with his intimidator code- pm him on here. All three of my guns run rabid code, and can be capped down to 2 or 3 BPS if needed. There's a straight millenium mode, which is 2010 legal, and a user defined ramp which will allow you to keep up with any future rule changes.
My last one was about £25 for a reflash.
