Fule pump question

Guys,

Anyone know how much horsepower (roughly) a stock 4.6 fule pump can handle. In my current set-up I am running lean at wide open throttle, and wanted to know if it could be a fuel pump issue.

It is probably a tuning issue. I believe that stock pump is good up to around 500rwhp though. I am not certain, but I've been told. I have a focus pump though.

I don't think the stocker can handle that much, probably closer to the limits of the engine w/ bolt-ons, w/ Boost-A-Pump, a bit more...

How old are your O2 Sensors?? What IDC are you at, at WOT??
