Bmw M4 + Jb4 = Wow!

[Sir_M4]

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.

This may sound stupid, how easy is it to remove?

It took about 30 - 40 mins to install but it includes a stock map if you ever needed bring it back to stock settings it would take 5 - 10 mins.

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.

So you did the stage 2 install? How is map changing done on the f8x?

We did a stage 1 install only since I'm awaiting for down pipes. According to John from Eurowerks you can do it yourself but it will not indicate or show you the map has change so he has advise me to just bring it back to him if ever I need to put it back to stock settings.
