e.g. roughly=20 speaking boost PSI =3D (MAP - height=20 thousands)-30/2

MAP =3D 42 @ SL=20 =3D 6PSI

MAP =3D 48 @=20 10,000 =3D 4PSI

Does this=20 makes sense, or am I still missing something?

Assuming you=20 meant 14 psi for the last example, I think you've got=20 it.

I = also agree=20 (gasp <g>) with Marvin that the boost gauge will no longer = be useful=20 after you prove that you can't push the turbo outside it's normal=20 range.
