Old AIR Valve Improvement (??)

[MFM-70]

Looking for confirmation that I should do this upgrade:

I have checked my A.I.R. valve hole alignment from the regulator to the main body and found them to be misaligned by a little more than 1/3 of a turn when the valve is assembled and the logo etching matches up.

Should I:

1)Leave it alone?
OR
2) Drill a second hole in the regulator that aligns with the main body hole?

This to improve flow and reduce shootdown.
I run Co2 and am trying to perfect the installation of my R/T on/off valve.

I am a Mold Maker and therefore have no worries regarding the machining aspect of this question. (not meant to be arrogant-just removing any concerns)

All input is welcome, so long as it does not try to get me to ever sell my mag or references my Mom in any way.
Thanks

Don't go too far into the back reg. I screwed up my first one doing that.

i think the RT/hyperframe/booyah on offs flow less that a stock AM/MM on off just because the pins return force is harder so it opens up faster

but if you got good trigger hygiene then youll love it

also the LVLX bolt puts less force on the sear allowing the on off pin to open quicker, also make the trigger pull lighter

I would drill it. I drilled mine. Its very easy. Just make sure you drill on a bit of an angle so that the hole ends up on the front face on the inside of the back section. You won't have any problems.

Drilled a .093" hole at 61.5 degrees and it came out nice.
Seems to have more "pop" than "puff" now.

Will need to chrono but it seems much better.
Thanks
