How good is a 1.6 Fuel Pump?

Wait, depends.
Seriously, it depends on the setup. If it's the original pump, I'd recommend changing it anyways as it's surely weak. Since you should change it, get a Walbro 190HP. Also, check out the search function and you'll find that fuel pumps have been discussed more than once in the past.

Don't follow my example, but I still have the stock fuel pump (220k miles) and it went through 12psi (~200whp) on my voodoo setup for over a year with no hiccups.
With my new 2560 setup however, I will be using a Walboro 190.
Edit: only to replace an old pump. Or I may just put a lower mileage stocker in.

Here's the long answer.
It depends on how you want to make that power.
Here's how a fuel pump is characterized:
250 hp would require X amount of GPH which you can easily calculate from the injector flow equation in the FAQ.
From the chart above its quite clear that you will run out of flow much sooner if you are using a higher base fuel pressure (via an AFPR or rising rate FPR).
If you're using larger injectors and the stock base fuel pressure, you have much more headroom. This usually requires an aftermarket ECU.
