I have a question for the community here. At a certain MAP my #1 EGT goes up 50 degrees. This has happened ever since first flight. It doesn't appear to be causing me any issues. An example of when it happens is when I pull power in the pattern to start a descent. Periodically, I've tried to figure it out. I've cleaned injectors, I've searched for intake leaks, I've gapped and cleaned and eventually replaced plugs. Nothing changes the behavior. Does anyone have any ideas? And are there any opinions on what long term impact (if any) there might be on my engine. See chart below for a nice example.
Bottom trace is MAP. Top traces are EGTs. #1 is the one that stands out from the others.
