I would never get the map done before the mods opcornsoda:
To be fair a lot of people start out with a remap early on with no plans for hardware changes, but then as time goes on we get the bug and end up with uprated fuel pumps, downpipes etc. So then another map to get the best out of the mods is required (call it Stage 2 or whatever).
But back to the original point, a cat back doesn't free up any more power and it'd be pointless to expect remarkable gains from an intake when the rest of the hardware is stock.
Rich put it more succinctly... It's a no.
