OK the results are from pressure testing

Without engine running at the MC 100-150 psi
With engine running At the MC 600 psi
lines to front 600 psi each side
line to rear 600 psi
With a 3 foot cheater bar on the brake pedal I reached 900 psi at rear with lots of pushing on the bar which was way over and beyond anything anyone could do with foot power on the pedal.
I did a search and found that 900 + psi seems to be the norm.

IS IT POSSIBLE THAT THE DARN POWER BOOSTER IS BAD ? Its new but ?
