I'm going to build a Procede/Meth/RB setup with my new '09 DCT. I have budgetted a new upgrade clutchpack for next year. This after my research for the ZF box and the harm tuning can do to a gearbox. I consider the ZF box as stronger then my new DCT box. But we will see.

Make sure to get someone to reprogram the mechatronics or else even with the new upgraded clutch pack you will still get slippage cause it will think your still using the stock clutch pack for the specific car it was programmed for.

Oh trust me, the owner will know, torque is diminished, and performance drop will be very noticeble.

Thats interesting, I am 14 months owning my DCT 335iS and have done over 100 launches, 35 in one 90° hot day - recorded and witnessed, and perhaps done more launches than any N54 DCT owner and still running strong.
Have I expereince slippage, yea sure, but the slippage was due to driver error and not understanding how the DCT and its safety mechanisms work
