Default BM3 + JB4 - 08-04-2019, 07:57 AM

Hey new guy here (at least on these forums) and looking to see who is running a BM3 + JB4 combo. Currently, I am on BM3 Stg 2 E30 OTS, xHP Stg 3, ER ******* ********, MPPSK Exhaust, FTP Intake Pipe + Filter, FTP Chargepipe and NGK 94201 spark plug gapped to 0.22.

I have been reading about the benefits of JB4 + BEF and am also thinking about going with the Fuel-It CPI kit, so makes sense to get JB4 which has many beneficial features than something like Torquebyte which is just good for one thing.

What do I really need to know about BM3 + JB4 combo? How do I get the BM3 BEF map? Can JB4 help with throttle closure issues?
