You will have to wait to see what codes come up, but one possibility is the VNT is seizing up when you are pushing hard on the throttle, ECU sees an issue-goes into limp mode. But another possibility is a torn intake hose somewhere. I realize it's not the configuration but just had my pals AHU do the same thing without a check light coming on . One of the hoses between the IC and intake had torn, i guess no code set because it was one that was after the MAP sensor. When i had the same thing happen to me a few years ago, a hose had torn but it was the one just after the turbo- and before the MAP and i had a code

im guessing you got a vac. leak but who knows none of us are with your car so all we can do is guess. get the codes read if you dont have vagcom take it to advance or auto zone get them to write the code down and look it up on google

I ordered a Vag Com Cable last night, and I have software 709.1 on the computer. and I have no Vac leaks, Ive checked all the vac lines a few weeks ago and it only happens on hard runs....I spoke with Giles and we thinks my MAF is pooched

I had the exact same problem. I tried everything, from replacing the MAF and vac lines, and so on. Turns out the vanes in the turbo were dirty. Got it rebuilt, haven't had any issues since.

catlin maybe your VNT ingested some intake gunk from when you did the intake... and the vanes are stuck now?

pull turbo off engine.
pull the 5 little bolts out of the hot side holding in the center
pull the center out of your turbo, behind it staring you in the face, will be the vanes..
you may have to completely replace them tho. i never had good luck freeing mine up. maybe a torch would have worked better.

Let's start this off with...I am a COMPLETE moron...now with that out of the way here's the problem.
A few weeks ago I cleaned my intake and you need to get underneath the turbo to get one of the tubes off. I noticed the Vacuum line going to the actulator was a bit rough and looked frayed...I though in my head that needs to be fixed but I didn't do it and kept at cleaning the intake...I was laying on the couch when the light bulb turned on!...

if you have to pull the turbo apart, be very careful with those 5 little bolts, and be sure to throw some copper never seize on them before you thread them back in.

PULL THE VACUUM LINE OFF OF THE SOLENOID AND WATCH THE MOVEMENT OF THE VNT LINKAGE.
Sorry for yelling, but you don't need to pull the turbo to check for clogging or restriction.
Get VAG com and check boost psi specified and actual. That will tell you if the VNT is functioning properly.
My two cents

There you go. The ecu sees too much boost- goes into failsafe [ or limp mode] so the motor doesn't get blown. now to figure out why it's got too much. It may be any of the things mentioned,did you ever get underneath to make sure the lever moves through it whole range [about an 1" it think ]. Once or if it's free use the output test on vag-com to get if the lever is being moved by the ecu and solenoid. could also still be a torn boot

I'm Crawling underneath the car today and going to change the vacuum line going to the turbo, and going to check to see if everyhting goes thru its motions.
i get 2 different readings on boost on the VAG COM, one is 28PSI and the other is 21PSI of boost....and thats 3rd from 2000RPM TO Redline at WOT

That's strange that your boost reading are in psi and not mBar . Maybe i never used my vag-com to check boost. I know in metric it's 1900-2100 mBar. Do the conversion maybe?
