Being that you can tune the same amount of tables with a BEF it just comes down to MHD being a complete tune, not a BEF that relies on another box to control boost. Kinda useless and less safe using a JB4.
I've been doing a lot of research on this and I actually believe the JB4 w/ back end flash is safer because it will kick you into a safe map if anything goes wrong.

I'm currently in the process of dynoing, getting drag times, and logging both MHD OTS maps and JB4 w/ BEF maps to compare them.

Saying MHD is better than JB4 simply because it is a full flash is kind of biased/misinformation IMO. JB4 does more than just control boost as it does control/manipulate timing as well and you can also run meth as you said.

Both are fine IMO as long as you log correctly. My logs on JB4 w/ E85 BEF and e60 are perfect
