Just wanted to provide an update regarding my comments on the 3.45 diff and GTS DCT tune. I was previously using a "revised" aftermarket GTS tune and believe that had something to do with my issues. I had my car flashed back to the OEM DCT tune and then recently installed the OEM GTS DCT tune. The issues I previously experienced have not returned and I'm really enjoying this OEM GTS tune. I've been running in S5 at the track and plan to test S6 out at COTA in a few weeks, can't wait!
