Am I the only one having these problems?

I am telling you guys that everything has been checked. The o2 sensor has also been replaced and nothing happened. Also, I don't really believe that the fuel pump is overrunning the stock FPR because I have had that fuel pump in my car for a long time and have never had any problems.

Imagine that, what a coincidence.You don't sound like you are looking for advice but rather stuck on pointing the blame. Go learn about fuel systems and tuning before asking people for help.

An obstruction in either end would affect air flow, but more so through the compressor side of course. When it was run N/A was the turbo still conected to the manifold? Did it seem to rotate freely, even when at idel? Although a turbo does not produce boost so to say at idel, it should be spinning pretty well. If it is not then the compressor blades will slow the incoming air charge. Is the DV still recirculating? Like I said, I expect that you have already checked these things, but anyway they are possible problems.
Another thought, was the turbo shipped in the little foam "peanuts"? If so maybe you could blow high pressure air through the exducer and see if any blow out through the front, like they could be lodged in there where it starts to taper down thus choking the air going in to the turbo...

i say, get an adjustible FPR b/c i gauranty that your fuel is sky rocketed at idle, it is a $150 mod that you will pleased with. it doesn't sound like the problem is in the maf but it could be, i hate these damb things, i would say delete the stock maf and go with a blow thru set up, their less restrictive, not as touchy, and their easier to tune. You can also put on any size intake you want!

If you re-placed the FPR with a stock one you still wouldn't be able to see what the psi is at like you would with an adjustable regulator with a gauge. To be honest I doubt it's the FPR at this point, and probably a restriction in the i/c piping, i/c, turbo, bov, etc., basically everything on the charge side of the turbo should be checked for restrictions.
Does the turbo spin freely by hand?

I think that EVOONYOASS could be on the correct track with the FPR, but I do not think that the car would run in N/A form if it was dumping too much fuel. It would still flood out which would kind of disprove that theory, but it is still worth looking in to.
Anyway, see if they can run the car N/A again while the turbo is still on the manifold. Look to see if the compressor turns smoothly, actually there are two things that you can do on this step. Our car will run without the MAF at idel. Run it with the maf unplugged N/A and look for the compressor to be spinning. If it spins then it is free and you will still have to blow air through the exducer to check for obstructions, but at least the turbine section is spinning it up. Next, use some of the tubing and fittings that you already have and hook the MAF up directly to the throttle body, basically run N/A through the MAF and see if it still runs well. If so then you have chased the problem down to a flowing issue with the turbo itself, like I said, it is possible that something is chocking up the compressor housing internally. They are rather easy to remove in order to check, but be careful on removal and re-installation so as not to damage the compressor wheel.
Let us know what happens.

If you would like, I will call TT up right now and have them replace my fuel pump with another fuel pump to test your theory. Also, the FPR was changed out, its not like we have not checked it.
The fuel pump will continue to over ride ANY stock fpr that you install because it is sending WAY TOO much fuel to the regulator and over riding it.
Call the shop and ask them to put a guage on the fuel system and see what PSI the system is at. That will eliminate my theory. Good luck.
