Which tune for BMW 2012+ N55?! | MHD or JB4?

Just a quick Video of my decision between JB4 & MHD + what it takes to unlock the DME to be able to flash tune it.

Does anybody know if I can run mhd now without worrying about this being locked? I know this was a big issue back then. Let me know if anybody knows, I have a 2012 135i n55 and I’m looking to get the mhd or the jb4 should I be worried about this.

What about a back and flash, some say the combination of both is really good

How much HP you gain from MHD and How much from JB4?

Are you FBO?
I have a 2013 also and I’m still not sure which one to get JB4 or MHD?

I have a e92 335i 2012 sadly I’m sure mine is locked, is it a hard process to remove the dme and put it back. This would be a first time for me doing this job. I really want a MHD but I’m running into this issue
