Our boost by gear works completely differently to how the sprint works. We would not recommend trying to edit tables with HPTuners after writing our custom operating system, we have no control over how they modify the calibration which could cause issues with the vehicle depending on what they do. Our Custom OS includes extra checksums which they will not be reading or updating, along with lots of extra code and tables which they also will not know how to modify correctly.
What is reason you need to use HPTuners at all?
