mods?

Faulty DV maybe. Slipping clutch another possibility. I've read about jerkiness when a DV is going out, that's why I threw that out there. Not sure though. Good luck.

Same thing has been happening to me, gona check for bad plugs and vac leaks?

No mods...I need to have someone check it i guess...whats the DV by the way? (car illiterate)

coilpacks or plugs is my guess... sounds like its only happening at WOT.

just start with the spark plugs, takes all of 10mins to do and $6-10 in parts. If it was the diverter valve (dv), your car would slow, but not jerk when the boost kicked in.

Traction control? lol

If you slam first>second in my car with traction control on it bogs it and makes it jerk. But I'm fwd too.

My guess is the coolant temp sensor is malfunctioning causing the ECM to freak out and cause miss-fires. If you have a VAG COM you can monitor the miss-fire counter on data block 15 or 16 i think to see if its missing.
That and you can check the CTS sensor at data block 3 i believe, if it drops to like -40 or something crazy when your driving thats your problem.
