Fresh M20 high RPM loss of power

[jlevie]

When the WOT switch in the TPS is closed the DME uses intake and engine temperature, rpm, and AFM data below about 5000rpm. The AFM maxes out there and above 5000rpm the DME uses only temperature and rpm data. If the WOT switch in the TPS isn't working the DME does not know to ignore the AFM data above 5k and use the built in WOT maps for fuel & timing.

Also, is there a way of testing my fuel pump? I'd rather not spend $200 on a part I don't actually need.

The pressure and delivery volume tests in the Bentley will if pump (or the FPR) needs to be replaced.
