Default 2014 M5 and JB4 stage 1 tuner - 01-10-2018, 10:15 AM

I recently installed the jb4 on my M5. Not knowing much about tuners I have questions as to what I do next With it? I've heard something about an upgrade but not sure what that would be. How do I use this tuner to my advantage. Can someone help me with the steps I should take to open up this car even more?

There is JB4, and Stage1. Do you mean you're running JB4 map1? Seen the thread for it? First steps would be to log and evaluate map1 to see how the car is running.
