Two things about over pressurising.
1. The increased pressure increases the force on the firing valve. This (a) reduces the ability of the hammer to open the valve, resulting in lower fps, and (b) causes the firing valve seal (top hat) to deform giving permanent reduced performance.
2. And most importantly, I believe the cylinders MAXIMUM SAFE WORKING PRESSURE IS 200 bar.
