Bmw M4 + Jb4 = Wow!
So this morning we installed the JB4 tune on my M4, Thank you to Kris at Superior Auto Design on recommending me to John from Eurowerkes. The performance and increase of power is AWESOME! It was very noticeable and the VALUE of the tune with the cost is very doable compare to others.

Its not as quick or easy to take out as the e9x chassis. If you have all of the sensors connected its simple to undo but a PITA to get to the fuel sensor.
I needed to disconnect the EWC on my car and it took me about 20-30 minutes to do it.
