Let me start off by saying that this transmission tune is by far the best thing I have done to my M3 yet. Turn around time for tune was as promised. Decided to play around with my car for about a week before leaving a review. I noticed a difference immediately after the first initial drive. Downshifting is now almost unfelt compared to the sluggish head bobbing downshifts prior to the tune. Auto mode is a lot smoother, and up shifting using paddles/shifter is MUCH more responsive like a modernized vehicle. All I can say is wow, my SMG was brought back to life for a more than reasonable price and easy DIY.
