02 Excal low velocity problem

I have a recently aquired 02 Excal. When i got it it was firing at 260fps, and no matter how I adjusted the regulator it would not go any higher. As a matter of fact, at a certain point as I was increasing the pressure the fps would start to drop. I ordered a tool kit and orings and rebuilt the lp reg ( a soda can) and the sidewinder. It still will not go past about 260fps. i turned the dwell up to about 11 to 12 to get it to 290, but it has a +/- 20 fps error. Any help would be appreciated. If it matters, it has a WAS board and is stock other than the soda can. Thanks

After looking at it closer, it appears that the bolt carrier on the end of the ram is loose. it took about 4 full turns + to tighten it. I'm guessing that is the reason for the erratic behavior of the gun.
