alright my e-99 just started having this problem. with my 14oz tank i have no problems and it shoots 280 fps and everything is happy. however when i switch to my 20oz i have problems. the fps spikes up to 370+ fps. making the velcity go down as far as it can go it is 340 fps. any clue how to fix this. i'm stumped and the only thing i can think is to clip off the spring a bit. the 20 works fine in my other guns, so i dont think that it is the tank. i just dont know

A spring kit would be a better solution than cutting. I've done both and the problem is that you can't make the spring longer again...but you can shim it.

A kit shouldn't be more than $5-$10 and will have at least 3 hammer springs and 3 valve springs of various tensions. Allows for a lot of options with no permanent changes. 32 Degrees and madman (?) make a 9 spring kit (But three of the springs are for old style valves and you'll just use the other six).

If I had to guess, and this is a guess, why the velocity changes just with that one tank, I'd say that for whatever reason the larger tank is sending a little liquid CO2 into the gun which is causing the extra velocity. It won't harm anything on a gun like a Spyder, but it'll cause your velocity to climb.

yeah co2 is inconsistent since its in the tank as liquid form if you want to see constistency go to hpa

Also try a anti-syphon tube if you already don't have on. C02 is also affected buy temperature. The warmer it is the higher the bottle pressure. Installing a good regulator like a Palmers Stabillizer could correct this issue. Palmers were designed with C02 in mind and as the name implies it will stailize you C02 perssure and even work like an X-chamber.
I put one on My Imagine and it works great. I even put it on my Ion with an anti-syphon tubed tank and it worked good on that also.
