"Centercut"My ES was about 30 fps with the FX regulator, but I bought the Bobcat used, so I can't say it was like that when it was new. I'm also not sure about the markings on the HUMA. Huub (at HUMA) told me that they set them up with a precision pressure gage when they are made prior to shipping, and you can request a specific pressure when you order. I requested 155 bar, and my regulator pressure gage shows 165 bar. Its more than likely that my pressure gage is the item that's not showing the correct pressure. Without an actual regulator pressure tester like Ernest Rowe uses in his videos, I'm not 100% sure what the regulator is set at.
Centercut, is the Bobcat receiver the same as the Royales? If so you can get a fitting from Best Fittings ( I believe that's their name) that lets you check your regulated pressure directly from the receiver. All you have to do is unscrew the stock bolt stud and screw this fitting in and then attach a good gauge.
