What would cause the fuel flow to drop during low rpm? When cold its about 5-6gph bu it drops when warm to about 1.

I too have a IO-375 with dual Pmags and the FM-150. Idle was unstable and hard to adjust. I found three issues and things are much better now - still not perfect however:

- the diaphragm in the flow divider had a leak from the very beginning
- the spring in the flow divider was installed incorrectly so that I always had
max flow through it.
- I installed smaller injector nozzles, went from .028 to .022.

Might be worth to have a look into this.
