I have had a 22 cal Airwolf for about a year. I have swapped out the cpu board for one of Jack's. It has 12 power settings, you can tweak each with 20 different sub settings, plus you can change the capacitor voltage and then you can tweak each of the 12 settings by a factor of .95 to 1.05 in .01 increments. That's 2400 settings not counting the capacitor voltage change. The display also shows remaining shots. Right now I am at 204 bar and have 220 shots remaining at 1.03 times power setting 7 shooting a 14.3 crossman at 840 f/sec.
He also has an extreme version of the board that will get 50 ftlbs in 0.22 from 250 bars-220 bars with a 29 grain pellet and 10 equal shots. While these tanks are tested, supposedly to at least 1.5 times I don't fill past 230 bar. By example,
If you fill up to 230 bar at 41 deg Fahrenheit and the temp rises to 77 deg Fahrenheit your bottle pressure will be 246.5 bar, at 85 degrees it is 250 bar.
