Boost - What does it mean to a 4.0 xk8?
I hooked up my OBDII to check my throttle position and saw a -10 Boost.
The throttle position (after adjustment) was 100% but I am wondering what the negative Boost number means.

It's measuring the vacuum in your intake manifold. Changes with engine speed, etc.

The MAP sensor in these cars is before the S/C so it will never show a positive number.
There isn't a pressure sensor after the S/C so you can't get a real boost measurement over OBD.
