Google around for the various discussions. In my opinion the benefits are not at all worth the price.
Not trying to argue, I really appreciate any comments against the mod. Just trying to understand it better.

I can see how what you say is true when you're going after 0-60/quarter mile numbers or seeking more power on the dyno sheet. Not gaining anything there really, just sacrificing top speed and shifting more often/sooner. I rarely have my M3 above 90mph, and when I do an occasional HPDE, I rarely exceed 140mph.

My ultimate goal is to improve seat-of-the-pants roll-on feel when you're in 3000-5000 rpm range driving around town. 14.9% more torque sounds like it should help.
