Whats a better upgrade to change my expansion chamber and install a new and better one or to install a anti-siphon tube to the CO2 tank?

Anti-siphon. Definately
This assures that NO liquid Co2 gets to your internals no matter how fast you fire. An expansion chamber will not work as desired at high ROF.

In case you didnt know an antisiphon tube is a tube that is put into the tank. It is bent upwards so that no liquid co2 gets sucked into it. (c02 tanks are only 3/4 of the way full of liquid when filled)
So imagine taking a soda bottle and tilting it sideways...kinda like that, with a tube bent towards where there is no soda. thumup:

my shop charges 10 for the tube and installation, but, from what I hear, most shops charge more.

Really? Ours does it for 5. But that was only once. Im not sure if it is still 5$. 10 sounds right to me.

Some places might install it for free if you purchase the anti-siphon tube from them (depending on how much they gouge you on it's price). It's worth trying :) I wouldn't bother though since the ASA is downangled on the E-99. You're not going to be sucking any liquid (a full tank is only partially filled with liquid) unless you shoot towards the ground.

I just ordered my siphon tube from Ebay with a 20oz tank. The local bastards "knew what I needed" ($200 nitro tank) and didn't want to really install anything for me. :? It's not a really hard install anyways.

The easiest way to tell is if you see large fluctuations in FPS or larger then usual clouds leaving your barrel. Keep in mind though that in cold weather you will have extra condensation even when not shooting liquid.

Yep. like I said in the above post the dropforward for the ASA puts it on a downward angle so you won't suck any liquid unless you point the gun down while shooting. Since you won't be sucking any liquid an expansion chamber won't make a difference either. If I were you I would take the money you were planning on using for the chamber and go with a decent CO2 regulator. This would be the best way to maintain consistancy from shot to shot plus if you reduce the operating pressure of the Spyder down to 600 or so with new springs you will be able to shoot more PBs in colder weather without the FPS dropping, along with a quieter report. This really isn't necessary though if you are happy with the way your gun already shoots.
