I recently purchased a bone stock 2014 CLA 45. While I do enjoy its performance I would appreciate a little more performance especially as it concerns throttle response. Since joining this group I have noticed there is no shortage of companies offering packages to improve the performance of the car. What I would like to know is if there is a preferred company and package that the majority of people here have and are happy with. I am located in Stuttgart Germany (yes, the HQ of MB) and am not able to send my ECU off for two weeks while it is programmed. If I could find a shop here in Stuttgart that has a chassis dyno and could do the install that would be ideal, however I am more than able to complete simple bolt-ons myself. I appreciate any and all feedback and consider myself to be lucky to be part of the AMG club.
