i know how to use my lpr. i have it at two turns in but then i use my reg to adjust the velocity. after i adjusted my lpr i had to turn up the reg to get it shooting at a higher velocity.

And dont you use the lpr to adjust the movement of the bolt not the FPS. I read this in the Dye forum.
if you lower it to much it wont operate but having a lower pressure needed to fire the gun would mean less air is required to fire it which would mean it would get you more shots per tank, and yes you use the hpr to adjust velocity but the lpr is used to fine tune it as said by smartparts, maybe im wrong but its what ive learned/been told and its worked flawlessly for me, j yim i believe you said youll be at OA this sunday? Ill show you MY quest and let you see what using the lpr can do to a quests performance

Its called sweet spotting your regs. How I do it and this comes from my matrix knowledge which should translate to the quest spool valve.

1. Set the lpr so that the gun cycles correctly. Then give it an extra 1/4 turn or so maybe more you want to set it a little higher than normal.

2. Get a chrono and adjust the HPR to achieve the desired fps

3. Begin lowering the LPR while chronoing you want to lower the LPR until you see a velocity drop. Once you see a velocity drop turn the LPR back up about a 1/8 turn at a time until the velocity comes back up.

thats how i do it seems to work for me.

There's a price you'll pay for trying hard to become whatever they are and saying whatever they say.
