Rolling road dyno

Hello everyone

This is my first post. I've been on rolling road dyno few days ago. Power and torque looks good. AFR has improved as well.(previous dyno showed AFR 10.0). The only downside is something wrong over 4500 RPM. Does anyone know what that it mean. Someone said that can be a clutch problem. I'm asking because I think about remap and I want to be sure that everything works perfect.

Power and torque was measured on the wheel. Car is unmodified except supersprint unsilenced Y pipe.

Thanks, Peter.

I don't know much about rolling road tuning. But a thought if the clutch doesn't slip at 4,500rpm, can't see that being a problem.
But if you have had the centre box removed, it may also be causing problems with the air-fuel ratio sensor/ oxygen sensor causing too much exhaust gas temperature.

Or confussing the original ecu settings with that centre box removed.
But as i state i know nothing about rolling road tunes, just trying to help really
