Given my setup--- drop-in filter, header-back exhaust (front pipe without the 2nd cat) and Perrin intake hose ----what would you run?

Headerback means your exhaust is from the header, back. So you have an overpipe, front pipe, midpipe, and muffler. That does not mean you have headers. So you should only run the drop-in, all cat-back map with whatever octane and timing/fuel you choose. Do not use the all-headers map.
