Given that M2 uses same IC as m235i you will be fine with OE IC.
Here in UK I'm using OE IC with jb4 catted DP on pump fuel and getting 400/460 crank power/torque on map 6.
You can try logging in map 5 to see how boost, AFR and ign av are. Map 1 gives +4 psi over stock and map 5 should exceed this easily and safely.
