Car Starts But very hesitant under any load

[slowAWDTSi]

Let me start with some background info. The car is a 90 Eagle Tsi AWD Built motor. All leak tests have been done. I have a leak around the throttle body bolts, very minor compared to the problem Im having. A set of stock injectors are currently in it for diagnostic purposes. Along with all stock fuel system except for a Walbro 255 w/ rewire. I recently swapped a 91 ecu and harness into it and so far its working fine.(problem existed before the swap also) The reason for doing that was to help eliminate some of my problems (which I will get to). Ive replaced most of the sensors with the replacement harness and the O2 sensor. The car starts up and idles alright. The timing is right on with the 800~950 rpm.
Ok the problem is, when the throttle is pushed at all it wants to fall on its face. Like the intercooler pipe is blown off or has a massive leak. It also feels like the timing is being pulled or is getting flooded with fuel. When you go to drive it the turbo immediately starts to try to build pressure (like is loaded massively) but it has no power at all. Just in tinkering with it I took the CAS and advanced it quite a bit (no light to reference when i did it) and it ran quite a bit better but still loading up. I'm currently waiting for a new logger to check all the data (old one got stolen). I was either thinking phantom knock somehow or a stuck injector? But at the moment I'm completely lost. Also Im not counting out the timing belt could be off a tooth at the crank.
Any Ideas will be appreciated

Ive swapped it out with another and same results. My new Logger should be in this next weekend, ill have to hook it up for more info

*Update*
Starting to look like the cam gear dowel pin may have sheared. It might be off a few degrees, but I have to go check myself to be sure.

Very weird problem, but all the ideas that you had could be or may contribute to it. Wait until you get the new logger and see what you can come up with and go from there.

Fix your boost leaks first (known problem) . There is no minor boost leak .

*Update*

Turns out the car is running extremely lean! Pulled the Exhaust mani to fix some leaks the back side of the valves and the exhaust runners were gettin kinda white. I fixed all of the boost leaks. Also cleaned out the throttle body and reset the timing and idle speed. The car doesn't fall on its face anymore but it still has no power under boost like it should. The only thing left, is the fuel pump. If I remember correctly the pressure when I had the adjustable regulator on it was fluctuating some times. The relay on the rewire is getting a little to hot from what I remember. I think the pump may be dieing. (Its a 255H walbro) Looks like I'll be ordering a new one, but Im gonna try to find my old stock one first.
