I plan to end up with DP, Cold air intake, Catback, and maybe, eventually an intercooler upgrade. Figure just with the first 3, would I be best off with an ECU upgrade or the Apex power FC? I will probably gowith the M2 ECU if I go that route, but the cost difference between the PFC and M2 ECU is only like 25-30% or around 300 dollars. The PFC will have tunability but I am not sure I trust myself , or many shops, to do that and the ECU upgrade will need to be reflashed anyway if I changhe upgrades correct? I am basically looking for best/ safest performer of the two options.

The PFC comes pre-mapped for the upgrades you mentioned. I myself like the tunability of a PFC especially if your planning on adding more to the car later. Plus with the price of PFC's currently under $900 with commander from Japan, it gets my vote

The PFC base map is not really intended to be driven on. It's a map that is loaded so you can start the car and then begin adjusting and tuning for your specific car.
