Ah I see. I have the turbo shaft speed sensor as well. I think at 1.6bar at 8000rpm I have around 111k rpm. Max speed rated at 127krpm. same as 9180. Some head room but close to max out.

I only use the turbo speed to reduce boost solenoid output when its approaching shaft speed limit for safety. Not sure if there is a way to tune fueling with turbo speed input.

I guess my question was if I will have detonation/knock as limiting factor
