Default Fuel Pump with NO2?

I've read and heard conflicting stories about when an upgraded fuel pump is needed when running a shot of NO2. On a 93 LT1, at what point do you need to upgrade your stock fuel pump to a more powerful one? 100hp...125...150? An when doing so what brand/model is recommended?

Thanks,

Eric

Walbro GSS307 - Any shot. I learned the hard way when it is a good time to upgrade the fuel system.

Go to racetronix.com. They have a great in-tank fuel pump upgrade kit with a super wiring harness. The stock pump is supposedly good for 400hp. I changed mine. It takes about 15 minutes.
