Max power on stock fuel system

What is the most whp you guys think can be run on the stock fuel system. I'm looking to get a deadbolt upgrade on my vf39 and hoping to avoid the cost and labor of the fuel system upgrade. What IDCs are you guys running with your stock injectors and pump.

thanks

I'm looking to install a vf30 and sti injectors, would I need to upgrade the fuel pump as well? What about rails? Where do they come into the equation?

fuel lines and rail are fine unless your running a really big turbo/ lots of boost.
