What defines Map 1 and Map 2? How much PSI and other for each Map?

Again the JB4 is a full blown module with more failsafe's and more customization. The "Default" map1 should be 4psi over stock, and map2 is 6psi over stock. Most commonly used in the N54/N55 and B58 (and others) The cars can safely take the 4psi and often the 6psi which is why there is an inflated gain of 100hp with some supporting mods. Those cars really shine with it.
Although from what I seem to understand/feel is that our Electronic wastegate might not let us reliably push so much more boost. I could never get to that darned connector (I tried once more and just couldn't get the C clip out enough). The 6 cyl engines boost around 14psi stock vs our 22.8 (or 25 in my case on JB4 logs).
