M5 tune suggestion needed

Alright I know this subject has been going over and over again but I still need some advice from you genius. If anybody can show me a portal to a instructional thread would be much appreciated.

So my current thought is between bm3 and jb4, cause I wish I can switch between maps. From what I know bm3 has loads of maps I can download and I can have tuner to customize it on top of that to make more power.
Jb4 on the other hand claims more HP gain just for the piggyback, doesn't seem to be as customizable as bm3.

Any insight and experience shared would be awesome, thx guys

Bm3 all the way. JB4 is decent but it’s basically a boost controller.. can’t touch timing or afr…. Bm3 with a custom tune. HCP has been making big power.

I have JB4 because the newer DME are locked still…

Who's tuning them? I contacted DME a few weeks ago, they said not yet...

Mission Performance has them unlocked, currently they are in "Private Beta Testing". They have a waitlist for when it becomes public, they posted it in June.

HPC in Russia has them unlocked and available for public, i think 7Even Force unlocked as well .
