I have been having issues as well. I have been running very cool at 12-14K at about 330 CHT’s. My EGT’s are below 1580. But my TIT is 1620 at 15.1 GPH. Im afraid to go too low and I feel i am get that roughness below 15GPH? suggestions?
Get the magneto timing checked

Lean harder. I pull back MP to 30.5 (as recommended) and lean my 22T fuel flow until I archive about 1550-1555 degrees.

Agree w Jim. Better get magneto timing checked. At 15.1 gph you’re already pretty lean and TIT should be around 1540 at that flow.
