There are 2 pressures that must be "balanced"
The high pressure and low pressure. Your gauge shows your low pressure. You prob already know this though.
Do you have a pressure tester for your hpr?
If so start there, set it at 225
Back the adjustment for the lpr out and start fresh.
Turn up the lp to 100 and chrono.
