I know my dealer, MB of Laguna Niguel sells Brabus stuff and also Fletcher Jones in Newport Beach is a Brabus dealer. <br> <br> Several have done a pulley kit on their automatic coupes and are very pleased with the results. 30 HP is 30 HP, automatic or 6 spd. I really enjoy my ASP Racing pulley and have had no problems. It does run lean so the fuel correctives have to be set to Stage 2 or 3 in the ECU by the MB dealer no matter what pulley you get.
