Walter Atkinson is an unknown quantity at this point
** With American Aviation intercoolers on my 73 P337, if I used the stock MP/RPM settings, I would get higher fuel flows and faster airspeeds, indicating to me that the engine was putting out more horsepower.**

Could that have been a fixed wastegate installation? If so, your observation would be correct. That will not be the case with a variable wastegate which alters exhaust backpressure.
