MAP works in conjunction with the TPS (throttle position sensor)... if the code is setting at high load higher RPM the voltage is above 4.5v. Clean throttle plate and check the TPS.

If egr is open or partially when engine is under load, it may set that dtc!
Block egr and delete dtc. Be aware it will set egr dtcs.
