Just curious. Is the M20M the one equipped with the
turbo-supercharged Lycoming that was retrofitted with external oil
lines to cool the exhaust valve guides a la the TIGO-541?

If this is indeed the case, 1350 is only slightly cool on your
airplane, 1750 is way too darn hot.

If the TIT is too high, there is not enough fuel flow.
High TIT at high power when the engine is working
hard is very destructive. Should be 1350 or so.

Are you talking about a specific installation in a specific airplane ?
The red line for my TIT is 1750ºF. 1350ºF is way cold on my airplane. I
don't think I could possibly put that much fuel through it.
