Congrats!! I am looking forward in hearing your thoughts after the tune and vehicle have gotten past the honeymoon period .

I should know the answer to this, but what is the boost with Map 1 on the JB4?

I am still debating if it is even worth getting the stage 2 over the stage 1. There is no need or real use with switching to different maps on the F10 n55. I can bump up the boost on the Stage 1.
