Try 130-140 on LPR, and reset board to stock settings. I used to run a Hybrid Verdict LPR on my Pimp. Hard to find, but much smaller and lighter. I ran a CP reg as a HPR. Lighter also. Make sure the Det HPR isn't turned up too high. If you turn it up too high past the sweetspot, then the pressure will actually start to drop. Also make sure you shoot as you adjust the HPR so you relieve some pressure, and saves your reg seat from premature wear.
Here is the manual:
Once you getting it shooting at the correct velocity, you can try to fine tune it and lower your LPR. Here are some settings you can try later:
