Does the ECU have a safe mode, possibly from a bad coolant temp sensor or any other sensor?
Do you have a boost gauge?

She still pulls hard in first and chirped in second, I did a 1 minute idle cooldown when I got to college, as far as I know all the. Sensors are good. No extra hauges

hmm, interesting.. so where is it loosing power then??
if it pulls hard through first and has the torque to chirp second.. why wouldn't it pull through all the other gears?
I haven't a clue lol

What about bad fuel? dirty filter? Clogged tank pickup? Or just the switch to winter Diesel maybe??
If you have a fuel restriction you won't notice it until you need real power (ie. 5th gear up a hill)

Scan 'er for codes, son... most of the time the ECU has some clues.

I know that my MK4 TDI will go into limp mode if raced/reved to high if coolant temps are not up to a safe level. It throws on the check eng. light.

I think we have the same problem on our 03 TDi wagon, no guts after 3200 rpm, smells propane like, my guess is c/c, especially after 388k km

Try running a good injector cleaner through the fuel tank or better yet, through the pump directly.
When were the injectors rebuilt? How about the intake manifold, is it clean or choked up. Also check the range of movement on the VNT linkage.
Do you have Vag Com to check your MAF readings?

13,000km Bump,
Car now Goes into LIMP MODE after extended periods at 85mph...4 hours at 85mph or 3000RPM the car goes into limp. I noticed it yesterday when I hit the first long hill in a Beautiful place in NS Called Cobiquid Pass(ALL HILLS FOR 70KMS) I felt the car having a hard time so I floored it(I was on cruise) and it had no power and lost alot goingup the hill. I manage to make it off the road and shut downa nd restated and it worked better for the rest of the trip.
on the way back i ran at 85MPH(140KPH) for 1.5 hours and she went into limp again, I shut down and restarted and it worked for the other 2 hours just fine at 120KPH.
Everytime i run the car hard the car gets gutless
Intake Manifold is Clean, New Airfilter, New Fuel Filter.....
I'm guess the MAF is Pooched but I know that it alone wont throw the car into limp mode, and All my Vacuum lines are connected and not damaged and all intake lines are connected firmly.....Please Help

Limp mode has hundreds of causes... you're gonna need the codes or you're just gonna end up throwing parts at it.

A MAF will make it feel like LimpMode. But its weird how after a long drive then has lack of power.
Can you reach down a feel for movement at the VNT. Better yet, start it and dissconnect the vac. line from the solinoid and watch it move.
Vag Com will really help in diagnosising this issue. Look at measuring blocks, group number 1, and the last channel will be MAF readings.
Drive it and have your friend check them.
I feel these TDIs are dumb as far as runabillity goes. They don't care if theres a problem they just run. You have to know what your looking at.

I'm guess my sister had the same issue before,hers was the MAF. But for me the first time it happened I had floored it and there was a brief second then it felt like the car hit a wall, and the second time it did it was when I came off cruise... But when I first bough the car it did that once, I pulled out to pass someone(day 2 of owning) and it loss all power, I chaned the airfilter and it didn't do it again.
