: thnx.. i was planing on messing with the reg but i wasnt sure, also, will 350 be too high for my field if the limit is 250 fps? : thnx as Greezly says, his is set to around 250psi. You can try moving it up slowly, to around 225 and that may land you at 250fps. If you buymp it up to 350psi, you may have to back the spring all the way out or even use a slightly lighter one, OR the additional back pressure will effectively close the valve for you. The idea of sweetspotting your regulator is along these lines, you back the mainspring out all the way, then with your regulator, you go up and down until you find the place wheere the mainspring and the back pressure are just right to give you your legal field FPS. At 350psi you may need to change the main spring to a lighter one, but otherwise it's not like you're stuck with whatever FPS your front reg gives you...
