Is it possible to order a reg piston for an ReTro that vents at higher pressure

Is it possible to order a reg piston for an ReTro that vents at higher pressure. This would make level 10 setup a lot easier.

Perhaps the new ones are set to a higher pressure than what I have, my retro is SN 005xx.

And what I'm asking is, does that vent at a higher pressure than what came stock in a initial run ReTro? I can shoot 300fps just fine with the shortest spring. I can shoot 300fps and a lot more with level 7 internals.

From what I have read, there is a way to adjust the classic valve reg piston to vent at a slightly higher pressure. That gives you some head room when setting up a level 10 kit. I don't see any way to do that with a ReTro Reg Piston.

Thanks for the effort tho. I do appreciate it.
