Zero out both regs
Raise your lpr to about 40
Raise your hpr untill it starts to chrono
Raise your lpr until you get to the fps you require
Fine tune to get consistency
That's what I do
The gauges on the testers arnt the best so if pos it might be worth changing them to a better quality one. The thread size is 1/8
Also clean your reg and lpr if its not new
The premium bolt is good well worth it, lowers the sound signature allot, a bit of a pain to get out though
