I should have said indicated airspeed. At altitude, indicated airspeed will read low relative to true airspeed because of the "thinness" of the air and the way airspeed is measured.

A boost light would be good. I have a fancy digital vacuum gauge that you can set to change colour when a certain setting is reached. It's very handy because you don't have to be looking at it to see the change point.

Why would running unboosted reduce pumping losses? Isn't it the other way around or are you referring to compressor/SC losses?

It would also be a good thing to have a fuel mixture gauge to see when you are enriched. I imagine that under boost, it runs rich. Keeping out of that zone would help your FE. I need one too.
