I have 2012 c63 amg with the development package, I bought stage 1+ supercharger kit and longtube setup from weistec everything was top notch down to the arp headstuds and a new gasket kit, got the car done late today started up fine but as soon as it see a load it start running like it has 7 cylinders, turn the car off, turn it back on runs fine, go to drive and give it and give a lil gas and it stumble, I would call weistec but there close, it sounds like it has a bad tune, but let me hear what you guys have to say about this.
