If you don't have the traction to take advantage of it, the DSC/traction systems will just cut the power to the wheels.

The M3 is already traction limited in lower gears with the stock ECU programming. The real benefit here is the subjective feel of the power band, and how the car may be able to pull in higher gears, where traction is not a concern.

So....don't be so happy about your DSC light kicking in more. Be happy about how much better your car feels in general and how it pulls at 80mph when you down shift and punch it.

And yeah.....I haven't done this yet, but I've just heard so many great things about the tune, both online and in person, that I will likely take the plunge too. I really don't care about the added hp, as the objective benefit is trivial. I do care about how it makes an already great feeling engine even that much more enjoyable in its power delivery.
Get bigger rubber in the rear then, problem solved. Honestly, the power is definitely welcomed, but I think my favorite part about what Benvo did to the M3 is the Servo. That to me makes all the difference, especially in M mode.

Also, when I was on ZCP's, my DSC light would flash very quick between 1st and 2nd. But it's not like it was completely out of control by any means.
