The Bikirom accepts what you put in, even if it is off the map as I had a 9,,250rpm limit when it was still mapped to 8,500rpm and it still would hit the limiter at the right RPM.
I think there are a few sets or just one and Matt has one of them. You can contact Charles like mentioned above but may take awhile before he gets back to you.
I am going to have a set made but will be custom for my turbo build.
