Thanks ED... Your 337 is a Reims ?

No not a Reims. Mine is a 73 C337G. However, the referenced information applies to all our reciprocating aircraft engines. 😊

There are turbo 337s out there with GAMIs installed. The one I just sold had them. My understanding is you can run the TSIO-360 lean of peak safely with correctly installed GAMIs, reducing fuel flow to under 12.5 GPH (per engine) in cruise flight at 200 knots TAS.
