loss of power at lower engine speedss

I've spent the last 4 days going through the forums, and I am stumped
I have severe loss of power below 3k, over 3k runs fine and normal.
So I figure it's not lack of fuel, I just replaces the PCV hose, it was
slightly better, happens after the engine warms up a bit too most times.
Having to over rev to start from a standstill is killing my MPG.
I'm going to start looking at the egr and dpfe sensor this weekend.
I had a check engine light last time, my car was in limp home mode
i replaced plug wires and coil and it was good, that was 3 years ago.
So what to look at next, vacuum lines all look and feel good.
My few engine mods are SRI and my TB.
Is there any sensors that need to be checked at 110k miles.

if only this modding stuff didn't take so much money
Mac SRI, FC 65mm TB, SVT 5 spokes
SVT brake kit, SS lines up front, SVT suspension
