You'll want to stick with the JB4 BEF's.

Agree - I would not cut out the JB4 (Which you'd have to do if you switch to the full-MHD-only maps). IMO [JB4+MHD BEF] > [MHD 2+ only].
What BEF exactly are you running?

Before you go and change your tuning approach, sounds like your next step maybe should be an LPFP upgrade (didn't see that listed), so you can support higher boost levels on the BEF.

What boost is map 5 targeting for you now? It can target up to ~19.5 psi with the BEF, I believe, but only if your fueling and mods support it.

What kind of fuel do you have access to - just pump, or can mix ethanol?

Impossible to guess hp #'s
