I know that BEF is only for jb4. What I do not know is if the bef is essentially a flash tune that is designed to work with a jb4 car, or if it just compliments the jb4?

Example the jb4 tricks the ecu nto creating more boost. Does the BEF alter the ecu boost directly? Or is it still looking at the jb4?

I figured options were jb4 with BEF and wmi or OTS with a standalone wmi controller. I just do not know what benefits the OTS route would have over JB4 + BEF.
