I have no clue what the problem here is BUT I cannot get my bushy to shoot over 230 fps right now. Everyone is boggled by this, maybe someone here could help. I recently purchased vapor valve, FMD Hosed with palmer rock, polished ram assembly and a vapor bolt from a local shop that parted out a vapor bushy for me. Im running the stock 2K3 PDS board. How i adjust my lpr is i tighten it untill my noid leaks then back it out a turn or more. My hpr i START at just below 120psi the rase it over the chrono to try and get my desired FPS. I have pushed my HPR all the way just below 300 psi. Im running the stock inline and a Center Flag LP Tank. Ive tried putting on a BRAND NEW palmer rock and a NEW WGP ORRACLE TICKLER REG to see if it was my lpr and it wasnt. And i tried a AKA Sidewinder in replacement for my stock inline reg... nothing i have tried has worked. and yes i have a new battery in the gun and i use a cp kit so i know im getting a good paint-barrel match. LOL PLEASE HELP!!!!

What are your dwell settings? Try incresing the dwell and see if your FPS changes.

he cant change dwell, he is using a stock 2k3 board.

Try starting off at 200 PSI and then play with your LPR. Instead of making the noid leak turn the LPR up till your gun fully cycles at a high ROF. Then adjust FPS via the HPR.

doesnt matter anymore... all the vapor **** is gone, im back to stock and im probly going to get a trix.

That's weird. I was able to adjust dwell with my 2K2.

the 2k3 board does not have dwell settings, the 2k2 and maybe the early early 2k3's had dwell settings

i got sort of the same problem but I can't 250fps.. with out having to take out the spring?
