JB4 on the M2
So i know this has likely been covered in another tread but can't find it.
How is the JB4 biggyback tune in the M2?
I had one on my old car and found it to be really great and I have the Bluetooth adapter and the app so was thinking of getting the N55 version.
Anyone have any thoughts?
