Default Boost question?

So I'm often asked what boost am I running? Honestly, I have NO CLUE! So I installed a gauge and I still have no idea. Give my a direction and information on how to find out.

Rick,

Whatever the gauge indicates at peak rpm under load, perhaps top of 3rd or 4th gear.
A non supercharged car, will not show any positive pressure on your gauge.

Things are happing WAY TOO FAST once you get on it to try and look at a boost gauge. Just log KPA and do the math. It's fun to see how high I can get that purple line.
And whatever it is now in this hot weather, JUST WAIT until its around 40-50 degrees and see what it is then

my gauge's right where i can kinda see it out of the corner of my eye... but then again, with a PD, it more correlates to throttle position, so i can usually have a good idea without looking.

it is a nice gauge to have to see how altitude/DA are affecting your airflow... or as my case was tonight, to correlate starting to run lean every time you get near positive pressure
