I have a newish (March 2021) 30 CAL compact with the newer FX gauges on them. It was SPAW tuned at 165 reg and sitting at 250BAR on bottle pressure. I decided to change out the FX gauges to the Wika 315 28mm gauges just because people on this forum has said it MIGHT be a little more accurate.
The bottle pressure gauge was the same. Testing it off the compressor it stopped at the exact same spot on the new gauge at 250BAR. The FX regulator gauge was 10BAR difference. The FX gauge said 165BAR, but the new Wika was at 155BAR. Is this still pretty common, even with the FX gauges being the newer ones to be this far off?
I have to go chronograph the slugs and see if I am getting the same FPS. It would be nice if I am still tuned and I am at 155BAR instead of 165BAR on the regulator. A little less wear and tear. Before I changed out the gauges I had a small leak from somewhere. Soapy water didn't find it, but it's about 10BAR a day. I am hoping the gauge change out might fix it. \
I noticed I could't take out the o-rings below the gauges, so I just added another one on top of the old one and screwed down the new gauge. Are those o-rings supposed to come out?
