What is going on here? I thought most of the people here were all about modding their cars? Someone just posted their new M5 with a JB4/HR M550 springs (

In my first post here after a test drive, saying the car felt slow, if I remember right more than one person said a tune would change that. Which comes back to why I want to mod it, yes, it feels like it could use more power.
