Umm, your sentence is a little hard to read, but I'll give it my best shot.

You cannot disable the items rendering in the pneumatic tubes, but that typically doesn't cause too much lag. Are you running mulitple Redstone setups (i.e. Timers and such)? That typically causes the most lag, not rendering repeated items in a tube.
