I installed regulators on my .177, and my .22 GK1s. Here are tips for those who are considering a regulator. I did not use a chrony.
BEFORE installing a regulator, first find your best shooting projectile. Note your power adjustment, and the pressure range where you get your best consistent, tightest shot group - this may only be 5 to 8 shots or so. Groups will shift with the tube pressure. You may have 2 or 3 decent groupings; select the tightest one, or if they are similar, the one with the most shots within the group. Make your notes of the best groups, power setting, and pressure range, etc.
NOTE: selecting the top of the pressure range will yield the most power at a cost of shots per fill. Likewise, selecting the bottom of the range will yield more accurate shots. If you choose to set your reg at the middle of your range, gauge errors will be less of a factor (gauge reading different than where you thought you set your reg).
1. Set your your regulator at your selected pressure, per the instructions. Install it. Re-assemble the gun.
2. Pressure up. Fire a few mags. Leave the power adjustment alone till the reg settles. You should be done. If not satisfactory, continue..
If your gauge reads different than your manually set value, like mine did, you may need to re-adjust your reg -but first try it where it is, while adjusting the power between groups. Note where you started before adjusting, then make very small power adjustments -1/32 of a turn (less than a 1/4, less than an 1/8, less than 1/16) firing a minimum of 6 shots per adjustment.
NOTE: Because your gun is now regulated, turning up the power past it's efficient operational range will WASTE AIR. You will hear it. If you hear a lot of air during a shot, check your gauge, you will see it has gone down 4 to 6 MPA for one shot. This makes using the power adjuster different for a regulated gun. You may only get up to 1/2 turn of usable upward adjustment.
4. If your results are not satisfactory at the current reg setting, and having gone through many power adjustments, return the power adjustment to where it was initially, then go ahead and re-adjust your reg - try one of the other pressures that grouped well. Make notes of what you are doing.
5. Repeat the above steps till you get good results..
Hopefully, this will save you time. I spent half the day.
