Depends on when you get your Pro Stock 2.1...most of the 2.1 came with software 100110. However, you should update that to the latest one with the V1.33 interface (along with software version 100422 if that is for stock)
Yes...2.1 speedo can go down to 5.0 mod motor, HOWEVER, it is my opinon, I don't like to push my equipment to its max limit. If it is running MOD, I would stick with the GT2 PRO simiply because I know it is a MOD motor speedo.
