the flashing lights gauge that moves form yellow to green to red is a AIR FUEL RATIO GAUGE, not a kr gauge, the flashing lights do nothing, it just reads the narrow band signal off the front o2 sensor wire and gives you pretty lights too look at and is completely inaccurate.
At start up the idle COLD psi should be around 70-75, and HOT idle( after its fully warmed up and roughly 5-10 miles of driving) should around 40 psi give or take a few.
If you start it up and its at 75 and then you go WOT right away I do not doubt that it would 100 psi, and it your the kind of person that does that your a ****ing retard, and you will blow your motor up. The Knock sensor's dont even turn on till 160* and befor that there is no way to hold back the car from killing itself at WOT.
as for the picture it looks like a stock pulley size to me.
