if you have an IS, stage 1 is essentially the same figures as IS. you need to tune it to stage II (or IS' stage I) for you to get any feel from it. The software you purchased allows you to choose either stage 1 or 2 (i think, i ordered it but didnt install it yet). But because our 35is comes with BMW's own stage 1, you need to use ESS" stage 2 (which is a stage 1 tune for the 35is) - does that make sense?

Btw, to the others reading it. Do you need any upgrades to handle the stage 2? Or can it run witth everything else stock?

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???
