I have 175 hours on the IO-540 now and MOSTLY have it dialed in where I want.
Most recent change was more restrictor changes to fuel nozzles to get GAMI spread to .2.
All cylinders run GREAT in cruise (350-375 degrees) and all cylinders are under 400 on climb out EXCEPT #6. It goes up to 411. I realize this is fully acceptable, but my anal retentive nature wants to “tweak it” more.
Here’s my question: Who has added a small air dam behind #6 to direct some air down the back fins? It would cover a SMALL portion of oil cooler hole with a bend in it to redirect air. Has this worked for anyone else?
