Upgrade for Piranha Question

[Spyder7]

I have a Piranha Pro, I was wonder if a new after-market expansion chamber and/or a regulator for my tank would make a substantial amount of differance to spend money on? Also i was looking to buy a smart parts on/off valve too. If you think i could benifit from these upgrades, please tell me and what manufacturer should i get. Also i was looking at a 12" smart parts all american barrel. Also if there is a better upgrade that i didn't mention, please inform me.

Your help will be appreciated
Thanks

Well my self I'd get a Palmer Stabilizer You'd set you marker too 350 fps then you'd set the stabilizer to where you started ,just when the velocity just starts to come down from where you started then at this time its providing most of the control over the Vel.Then you can control the Vel. with the guns velocity ajuster. what your doing is set the gun up too have consistent maintain velocities.

well the reason my name is spyder and i like piranhas better is that i've been using this nick for about 5 years. I like cars alot. Ferrari Spider, ect. any car with spider in it, i probably like it. As for the 'y' in it, it's easier to get that nick on e-mails and online games then spelled spider. #7 was my baseball number for 4 years in a row. Also lucky 7's. So that explains my name.
