Full Flash Tune + JB4 vs Back End Flash + Jb4

I am running Mission Performance stage 2 flash. Alex at Mission unlocked my DMEs and he is awesome. Highly recommended.

Obviously my limitation right now is the 22psi of boost offered by a Full Flash. (unless I update map sensors to 3.5 Bar- which I dont want to do now).

I am looking to push the car further with more boost - possibly 25psi. The question is, can I stack jb4 on top of my FULL FLASH even though it is not a Back end flash made FOR jb4? I am looking for a little flexibility so that when I go to events, I can simply switch to a more powerful map offered by Jb4 while keeping my mission performance tune as a BEF.

OR

DO I have to go with a BEF and stack jb4 on top of it as many others have done here?

Whats the difference between a BEF and a full tune flash? Obviously my cheapest route is just stack jb4 on top of my full flash, but I await others to chime in here.

BTW, i have SSP clutches, catless downpipes and K&N filters.

This is where BM3 makes a difference. You switch between maps with your laptop--between a BEF and a custom flash.

Curious to know what Alex will say about this.

Cheers, dude. Glad you got that beast set up to tear the streets!

Thanks! Yeah im super happy with the tune. The car is doing great!

I just feel that at some roll race events i just cant keep up with the mercs or other m5s on just a jb4+bcm.

Would love the ability of safely dialing up a "kill" map for these events. Something that would work with full race gas and 100 percent meth in the vicinity of 25-26 psi. The torque i already have (around 700) but i wish i could do close to mid 700s whp.
