Tuning HM1000x RAW making sense of shot string.

Great success. It may be good enough. Or you may move even forward if you want.

My reg was repeating within 25psi. Whatever inconsistency there was, wasn’t very noticeable on my gauge. I think if I want to be any more picky with the reg I’m going to have to get a digital gauge. 


I believe my next step is a stronger valve return spring. 

does anybody know the measurements of the oem spring?

You have put a peek seat in your reg. It may take some brake in time to properly seal.

I suggest not to do things in hurry.



As far as OEM valve spring is concerned I understand that you already have it. So what is the point of asking the specs of OEM valve spring. 



Further you might need just a bit stiffer spring. You are running the gun without balanced valve that I have installed. Due to that balanced valve high strength valve spring is needed. Since you have not made this modification, you just need a bit harder spring to reduce the spread.

On your balanced valve, did you have to go to a stronger valve spring?

Yes my FX style valve needed much stronger valve spring
