As a reference I have a SoftWare flash tune on my car and it holds power to 6500rpm no worries with peak power at 6300rpm. Not sure what that tells us. FBO with software 365HPATW.... familiar number !

I am no expert but how could you otherwise manage to extend the power so high in the RPM-range as compared to the engine in the M135/235i?
Could the boost curve be set so it does not hold itīs power as high in the rev range in the M235i for example? Usually I believe you do that to avoid excessive heat or because the turbo can not flow enough air at high RPMs du to itīs characteristics.
Perhaps someone who knows how M135/235 responds to SW tuning can comment.
