Default super lean over 5K?

I've had a problem with the fuel pump before, so I bought a stock one from napa like 6 months ago to try and fix the problem, before it would randomly cut out, as if it wasn't getting power, then randomly turn back on, so I changed it and now after driving for an hour or two, once I hit WOT in bogs or sputters like crazy and on my shitty narrow band it doesn't read anything?? I'm in the market for a wideband so I can know exactly what's up, Do you all think I should think about upgrading my fuel setup? IE dual feed rail, bigger injectors, walbro? I'm almost positive it's the pump that's bad but, I will need this stuff down the road anyway. Plus I need to hook up my MS after I get the boom sling and an LC-1!!

A decription of your setup, fuel pressure readings, and wideband readings would be real nice...

Stock fuel pump & rail are good for 225 WHP at least, assuming you're running properly sized injectors and not using an AFPR. Of course, you haven't told us anything about your setup...

His setup isn't in his signature like everybody else, so does he think we are mind readers?

Hey, if it goes super lean above 5k, then don't go above 5k.

get a wideband, asshat. I changed fuel pumps because mine died and cut duty cycle in half.
