Does anyone know where I can find a list of Benjamin pumper mods? Particularly valve/piston mods and who may offer the parts. I put a flat top valve and piston in my 1377 and the power increase is pretty impressive. I'm not necessarily looking for more power overall (no steroid) in the Benjamin just more power sooner. Seems like a more efficient valve/piston setup would allow fewer pumps to produce the same velocity that more pumps would in a non modified gun.
