Linear boost timing master?
Is the MSD btm linear? Or is it only 1,2, and 3 degrees per pound of boost? Im looking for .5

The MSD BTM retards timing by a set amount per PSI of boost. This is set with an on dash **** that is infinatly adjustable up to 3 degrees of retard /PSIG, and to a maximum amount IIRC it was 10 degrees.

Its 15, so by infinitely you mean, I could run .5 or 1.5 degrees per psi, not just 1 or 2 or 3..
