I did not notice any difference in Power/Torque after loading the ESS tune
I admit that I'm clueless when it comes to cars or maybe unlucky as well! The initial software load was unsuccessful, so I recharged the car battery for a couple of hours, and it worked after that. Did I not do something right, or my expectation of "wow" like what others have mentioned is just too high?
I have a 2011 35iS DCT, and according to the software upgrade it's for StageI. I guess this thread is for Stage2. I paid $995 and I thought I was getting Stage2???
