I don't know much!
If you would mosey on over to the MKIII section...you'll see that we have a couple people with this problem as well. Now you seem to have done everything that most people do to fix the problem...however there is one other thing that seems to be missing in your troubleshooting.
I woud check your air intake...all of it! Make sure you are getting proper air. Also you can go to a shop, and get them to check it out, get a second, third...maybe even a fourth opinion. With something like that, it could cost you $0.50 in tubing, or it could cost you the price of new cams?? (Timing would give a sputter, but shouldn't really smooth out over 2,500...but meh!)
I personally own an MKIII Turbo...well two of them, one auto, one 5spd....you can PM me with any questions you might have...I have a good general sense on things, but regretably a small amount of hands on time.

Our Supra’s, which art in the driveway,
Hollowed be thy power, thy mods are great, thy speed endless,
On the road or at the track. Give us this day free of cops,
And forgive us our impound charges, as we forgive those who are slow.
And lead us not into speed traps, and deliver us from the interceptors,
For thine is our car, the power, and the glory…forever and ever….amen.
