I found this at AudiWorld Forums. Just wanted to share in case you DSG folks havent seen this. Keep in mind that they are talking about the DSG in the TT 3.2. It may be a different DSG model than our own but at least it's some kinda baseline we can form theories on. I'll repost it here just in case the link goes away.

Hi Marcel,
I've been informed by Steve Cherry that your company has been working on a 400-HP turbo kit for the 3.2 engine in the TT with DSG transmission.
I'm very interested in the kit, as I own a 3.2 TT myself, and have a few questions:
1. Is the DSG transmission in the TT 3.2 rated at 350 or 450 Nm? The specs mention that it's the "DQ-350" (based on the MQ-350), which is rated at only 350 Nm (258 lb-ft). However I've heard a rumor that it might actually be the "DQ-450", which is rated at 450 Nm (332 lb-ft).
The DSG is "officially" rated at 350Nm, but this is the same "official " rating that our 6 speed manual boxes have.
2. Is this "rating" only enforced by the transmission's ECU (aka TCM), so that it does not allow the input shaft of presenting more torque than the rated limit (be it 350 or 450 Nm)?
This Rating is enforced by the ECM and TCM as a conservative limiter to offer a guaranteed LONG life scenario for the tranny.
3. Have you managed to re-program the TCM in order to remove the software limit on torque?
Yes.
4. What is the "weakest link" of the DSG, clutches/gears/etc?
The only limiting factor we officially have with the DSG is that we can not currently lengthen the gears to offer a higher TOP SPEED.
5. Have you tested the physical torque limits of the DSG (and if so, over an extended period of time?) to determine how much actual torque the clutches or weakest link can take?
AT VW's official request, we have built the factory a few single turbo equipped DSG Golf's. VW themselves have used our kits to stress test their DSG. Over 6000miles on the Euro proving grounds have been logged at FULL THROTTLE, 5500RPM launches with no glimmer of difficulties. These cars are FT400smic trim.
6. Finally, if you managed to re-program the TCM, have you found where the Launch Control code resides? As you must know, the LC programming was removed for US-based TT's and I'm trying to find a way to re-enable it.
We have ENABLED and manipulated the Launch control. You can now launch at 5500RPM in all our DSG cars.
Thanks in advance for all your answers!
Marc, this DSG set-up is so impressive and such an engineering marvel, that we will work this summer to convert our shop cars to DSG, even for the Twin turbo's. With one clutch handling one set of gears and the second clutch the other, we are able to manipulate the oil pressure to generate the grip force required to launch the highest horse power cars. We have a DSG specific kit, with software on the shelf ready for some LUCKY owner. Once installed, a 360 Modena doesn't stand a snow balls chance in Hell!!!!
I must be careful in reference of divulging the exact degree of testing that we have co-operatively performed with VW on the DSG, but hope to convey the sheer excitement I feel towards this set-up. The first run in the car and you will never think standard again!
