It can slow them down, drive them to one side, etc. I had similar problems with my mp5.
Extend your inner barrel, use slower battery or drill small holes in your silencer an inch or so past the inner barrel tip. You could change your cylinder but then you probably won't have enough air to fully push the bb.
Assuming it's not the foam.
Good luck

Back pressure, just like an internal combustion engine; an engine is basically an air pump, the forward motion is just a by product. The suppressor is like the muffler on a car. On an engine that back pressure is used to scavenge the cylinder for the next combustion cycle (one of the reason why those slap me on coffee can tips on imports don't do much).
In Semi there is enough time to dissipate the air.
You could also try pulling all the baffles if that's possible and then slowly adding them back one by one till your problem comes back. Then you can decide if you need a bypass like a bleed hole or so on.
