underdrive pulley

Considering replacing the underdrive pulley on my e92 M3 to squeeze out a little more power. I realize that it's $400 for the part and another $400 for install labor. I already have the Active Autowerke sport exhaust, AA test pipes, AA stage 2 software and aFe stage 2 intake (the one that uses the factory air box). Other than the pulley upgrade is there any other mods to increase power? I'm not ready to go forced induction yet as my motor has only 35k miles.
Thoughts or any experience with the pulley upgrade?

It's going to come down to what kind of gains you are looking for. Our pulley will add an additional 10HP. We also have piggy back modules that adds 40HP close to the same price as the pulley but you avoid that install cost of another $400. I honestly could not feel much of a difference in power with the pulley on the car, it did however feel to run smoother.

Also, here is a link to the pulleys and modules we offer for you E92 M3
