I have a mechanical diesel NA.
tasdrouille seems to have the closest idea to my first question. That being on a turbo diesel when a less fuel to air ratio is forced. Is the mileage any better. Such as when the intake pressure sensing loop is shut off or modified. And so far the consence seems to be that pumping losses offset any gains. at least if you got a VGT.
I have the timing advanced to the maximum vw recommends. i am setting it statically so wondered if there was a rule of thumb to set it by EGT.
