scooby350bhp

Hi, just wondering what the best is as im not looking for massive power, so was wondering what would is best for 340ish bhp

My current spec is

MY97
VF28 turbo, blitz induction kit, walbro 255 fuel pump, r160 diff, STi 3 V limited gearbox, STi gearbox mounts, 2.5 inch straight thro including de cat, equal length headers, Apexi ecu + power fc, currently mapped by Zen running 1.4 bar and running around 300bhp @ the mo

Ive got my 440cc injectors going in soon, but need help on whether to get the STi intercooler or FMIC

Any opinons?

Thanks
