14.7 is seal level. Im saying that it went to 19 to 20 plus above vacuum because when the motor is running, their is vacuum right. or u could say about 230 kpa total if that helps.

The pressure was 14.36 at the dyno location.

So with out boost the engine can get to about 0 pressure wide open witch would = atmosphere or theoretical 14.7 but was 14.36 in this case. Boost is all above that.
That's lower than what I would expect, but I'm not a meth guy:

20.00
-14.36
5.64 psia boost
