Green is previous best with with cams set to zero, and the wastegate control running out of duty cycle so hence boost tapering off up high.
Red is with exhaust cam retarded 4 deg, and no changes to boost control, with the boost naturally holding better in upper RPM. More fuel added due to wanting to ping slightly, and if ignition advance removed, power dropped.
