Ok guys. I have loss of power/pull on the top end. Mainly in 9th and 10th.
It's acting just like a fuel filter issue....Or boost sensor. Fuel filter is new.
Thing is. It will run like that for a couple hours and then kick in to how it's supposed to be and run strong for a while.... and then run like ####.
What would you say? Just replace the sensor or would you point somewhere else?

I'd had a similar on and off problem on a different engine - N14, turned out it was one of the injectors.

Fuel lines decaying internally might be worth considering.
