1.95, let me guess, 0xF8 in the fool cutoff table; at least, that's what
I have in mine.

I am using the pressure regulator on the wastegate method of boost increase...
I see the occasional 1.9, whatever that means since the guage is very
inaccurate.  I'm working on fixing that **** guage.  Now it reads 1.0
before starting, better than the 0.9 it originally read.  A fix for a low
reading guage _may_ be as simple as a 4.7k potentiometer in the line
to the computer (one end to MAC11B, the other to ground and wiper to the
trip computer).

I'm still working on decoding the MAC11B.  A boost upgrade may well be
as simple as reprogramming the table which activates the wastegate
solenoid.
