If you want bigger fruit you can continue to let vines grow but remove any new fruit they set, to let all energy go into existing fruit (this is how they make those super big pumpkins). But if you just want fruit volume, and not necessarily super big (but fewer) fruits, generally let the thing grow.
Thanks for the reply, I think I will just let the main vine keep growing and cut off any side shoots from there. There's a nice pumpkin forming (just the one so far), and I would hate to do something to ruin it, especially for how much garden real estate that plant is taking up!
