I asked him specifically about BMWs hp limitations for the e89 dct, but he indicated he wasn't really that concerned about it. He said that BMW was very conservative in their ratings, but Dinan has previously exceeded BMWs specs for the dct before. FWIW
I hope he offers a tune for the manual tranny. I am sure most Z4's have DCT's installed and that is what the test car has. I know there were 2 different tunes for the 335 depending on manual or steptronic tranny, different stages too. I figured the tune would be the same except for possible changes to compensate for the active handling throttle steering system (forgot what BMW calls this). I loved the stage 2 tune on my 335, can't wait.
