If you want to run at 300psi, then you are on the right track in needing some type of volume chamber to hold extra gas. Unfortunately, the only way that extra gas is going to get through the valve is if you make the air passages larger; the Tippmann LP valves have twice as wide of air passage that stock valves do.
Although, I noticed that just recently Tippmann started milling extra air channels in valve bodies. Here is what I mean: http://www.tippmannparts.com/index.c...&categoryID=13
I'm not sure when they switched, but my A-5 valve body had only 1 air channel on each side. The new one obviously has 2 per side. The LP valve had just a little more then this, the 2 channels were 1 big channel, there was no ridge seperating them. However, if your valve is this style then it should transfer enough air to run at 400psi or so.
Note, you will also have to get a lighter valve spring, and lighten your hammer. The whole point is to make the valve stay open longer, and release a larger volume of air at a lower pressure.
Oh, also, on the LP valve the pin is a larger diameter, I am not sure what exactly the point of that is or how it's supposed to affect blowback and such.
