First time taking my BW to the range today to get it sighted. Small orange target is sighted at 25 yards. Top 2 splatter targets and the diamond paper target at the bottom left are 50 yard groups.

For the 25 yards sighters groups, I played with no moderator, Sumo Donnyfl, and Donnyfl Tatsu. Groups with Sumo is the best but did bring point of impact down just a tad. No moderator shot the second best.

Regulator is set at 145 bar from AOA shooting 960 FPS with hammer at MIN, using 25 grain monster redesigns. I didn't play with the hammer spring since that speed and pellet weight is where it wants to be. I am pretty happy with the performance.

What caliber?

When you lower the regular to 130 bar, how many shots are you getting from 250 bar fill to 200 bar fill? I noticed when the regulator is set at 145 bar stock from AOA, my air full drops from 250 bar fill to 200 bar fill in only 11 shots ( one magazine)

I don’t know what caliber you are shooting but, let’s say you’re using a .22, so the 145 is probably too high.
I’d start at 120 on the reg and power wheel at min. Chrono and repeat at each power wheel setting and record results
if you aren’t seeing any changes with the power wheel setting, increase reg pressure 3-5 bar at a time and repeat.
generally the lower the reg setting is the more efficient the air usage
sometimes you can benefit from using a different spring:
