I've put about 75 miles on the car since the install. I believe it's a little quicker - BMW's claim of .2 better in 0-60 and the 1/4 seems honest. My car is AT so the torque gain is greater than the HP gain and I can feel a difference.
This isn't a balls to the wall tune - which anyone investing in it already knows. I'm happy though with a bit of extra HP/TQ and no warranty concerns on a car that I need to drive daily.
