Mapping and the JB+ I'm looking at one of these or would getting
both work? Not sure how that works.

You'd get one or the other. The JB+ quick install makes about the same power and is smoother, but lacks the lag reduction of the JB3 Stage1. For those who already have the Stage1 they can simulate the JB+ with it using firmware posted on BMS' site to feel the differences and compare. Although the install time isn't too bad with the JB3 Stage1 it's 1000% easier with the new JB+.
