Air fuel control derate?

[Rockycoon75]

Good morning beautiful I love you When it derates the boost stays around 5-10 when it clears it will go to 33ish. When running correct it was running around 38. Pyrometer runs around 7 usually but now that this has started it's pushing 8. I went to Albuquerque last week and I had to back out of it because it got to 9 and still climbing.

It did this a couple of times in the past but only for a second. Now it's happening quite often.

Don't have mechanical guages. I don't think mine is going that high at 1800 but will check it again shortly
