Put a jb4 in my 535.. I was really happy with the result.. I thought it was a huge difference.
So I am looking to do the same on the M.
I am going to keep the car pretty much stock. I want to do an intake but cant see spending 500+ for maybe 5 horses.
So what tune should I get? I am not looking to spend 3k so that eliminates the Dinan. Does that basically leave the jb4?
How is the jb4 on these cars? Is the stage 1 tune any good? Or is it a waste? Should I just go for the stage 2 if I were to buy a jb4?
So which tune should I go with guys? I really appreciate the advice guys.

You have several vendors out there providing amazing tunes but it sounds to me like you're leaning more towards the JB4. I would defining pick up the JB4+BCM and use map 2.
