I read the other thread and I think your problem is that the EGR is stuck slightly open probably because of carbon deposits. It is possible for it to fail without getting codes. It's been 6 years which is about the time that mine went on me. The EGR is supposed to stay closed at WOT and idle which are the places you are having troubles.

I think your FPR is fine and am not sure about the Chilton's pinch test. It doesn't make sense to me. Of course the pressure will shoot up if you pinch the return line. That's basically what the FPR does.
