You are using HPA right? Becuase I would think that even under ideal conditions ripping on CO2 the pressure will give over time.

One option might be to drill out the recock jets a bit. Thats what we did in the old days to improve cold weather performance. However, its a bit tricky is you can't just drill the hole larger, because the cupseal will not seat properly.
Instead, you can drill tiny holes through the brass core, or use a file/saw and cut "slots" into the existing hole.

Or use a siphon tank. That will elliminate the shootdown, and give your cycling a boost at the same time.

thanks fellaz, last night I used co2 becuase my Hpa was empty. I am gonna go it filled today and see if that works.

It burped off a good amount of rounds with no prob but then I went inside to grap more paint then it started not cycling. I had to recock it every few shots...

So would HPA be the answer?

I'd go for syphon CO2.

It imagine it would be easy enough to test if the siphon would help.

When firing full auto, point the gun in a direction so that the CO2 tank is pointed DOWN. Thus allowing the liquid CO2 to feed directly into the valve.

The liquid gives a strong pressure boost to the recock jets, and it also elliminates shootdown/chilling.

You have to be carefull though. I -think- you removed your bumper? Using a siphon will increase the cycle speed slightly, which is counterproduction to your final goal
