see a difference with pulleys?

does anyone have any experience with the Active Autowerke Signature Pulley Kit, or something of the sort? Does anyone notice a significant difference with using pulleys?

A while back some people used NST pulleys and things didnt end too well. I dont remember the details but a quick search or even google could tell you more detail. It was enough to steer the community away from using them as a whole, based on the observation that its rare to find someone with pulleys in their modification list in their signature

At least with the crank pulley, the n54's acts as a balance so that a balancing shaft is not needed. Reducing the weight of this particular pulley will imbalance the engine.
