I was thinking of upgrading the supercharger pulley on my 06 and also having the supercharger unit port and polished with new programming. Does anyone have experience with http://www.eurotoysltd.com/

 

keep away from any system that can reprogram the vehicle cause it will ruin your investment and upgrade to a regular program designed for the car.

and if you don't know what you are doing, then good luck trying to get help after you get all sorts of leaks and the like.
