Automag Regulator Piston

[LoveMyMagMoreThanYou]

This may sound like a newbie question, but...............
Should I buy the regulator piston in the Airgun Store that says it is set for the Level 10 pressures? Does that mean I don't have to screw the regulator nut in as far or that it vents at a higher pressure? I wouldn't even have to write this if the description was a little better.....

If your reg piston now vents before you reach your desired velocity with a properly setup L10,then you need the higher pressure piston.

That's what I thought it meant but I wanted clarification. Thanks!!
