I must say it do like the idea of what its capable of, but just changed my clutch also so still in the break in process and can't put it to the test yet...

THE PROBLEM....

I'm hearing some rear end noise, it's kinda like a whine... I'm thinking it's the fuel pump cause I was playing with the pedal( accelerating up hill ) to see if the pump would whine up cause the differential wouldn't have a change in speed. Anyone ever have this problem with the fuel pump? Or does it sound like my wheel bearings are about to go?

its your diff when you get an lsd they whine so im going to assume that the same goes for welded diffs.if you really dont like it you can go buy some additive and put it in

It's not bothering me just don't want it to lock up ya know.... Ok here's the new discovery, I turn the key on and go into the trunk and it's a faint screetch so I'm thinking it is the fuel pump... : ( so how long can it go on like this til it tries to fail on me and if I put in a Walbro 255 will it flood my lightly modded SOHC?

It wont flood it, thats what your FRP is for. It doesn't necessarily pump that much more fuel, just more consistent.
