What you paid to install pulley?

The AMS pulley requires no additional tuning, the stock ECU will fully adjust to the increased acceleration. Furthermore, customers have seen gains in fuel efficiency of up to 1.5-2.0mpg thereby making the pulley pay for itself over time.
Typical gains on the M113 V8s range in the 12-15HP/TQ range throughout the low end to mid-range where you need the power the most. In addition, they pulley also improves the way the transmission shifts as well because of the more free revving nature of the lightweight pulley.
On a side note, for CLK550 owners, high flow 2nd cats are also highly recommended and extremely inexpensive to do. The high flow 2nd cats compliment the crank pulley very well by boosting low end to mid range torque even more while still providing excellent top end gains.
Hope that helps,
