Now, they likely are raising torque limits that the transmission can handle so the increase is torque is likely true. However, a 50% reduction in shift time while claiming smoother shifts is hard to believe. BenzBoost would like to see some kind of data to support the shift time reduction claim. If the software is making such a large difference in the shift time it should easily transfer over to an improvement in acceleration figures.
There is no data for support and no pricing information either. Rebellion is going to need to provide more substance but M133 tuning definitely is continuing to move forward.
