What Tune Adjustments when Stacking (Cobb, JB4)

In preparation for future plans, I purchased a JB4 (ISO, FSB) to sit on top of my existing custom ATR tune (e85, meth, FBO, 450whp).

My flash boost is dialed-in perfectly (~18.5psi, no throttle closures, solid AFR, good timing). I'm running JB4 on map 3 typically (~60 additive), and optionally on map 7.

The question I have is, is there anything in particular I need to do to either my tune or JB4 to get them to work well together?

Thanks
