Default Fuel Pressure dropping to 45psi...

After doing a search here I come up with our LS1 FP being a constant 58-60psi, with a 2-3 psi drop at WOT. My fuel pressure is dropping down to 45 psi at the top of each gear at WOT and my injectors are way over 100% DS.

Anyone else have this problem? I'm assuming is either a restriction in the lines or a bad pump. Any info would be appreciated. Thanks.

I'm thinking dirty fuel filter/bad pump for the pressure problem...

The injectors are maxed out cause the computer is trying to get the A/F ratio correct and injector control is pretty much it's only way of richening up the mixture.

Is your car stock? How about the fuel filter? is it dirty? This would explain the low fuel pressure but I can't tell you whats up with the injectors.
