fmic question

I installed one on my stockish s5 t2 and the idle dropped to 900 vs 1500 prior to the install. Under stock boost, it goes waay rich, idles irratically. Do I need to upgrade my ecu for it to work properly? When it builds boost, it spikes to 10 and drops to around 8. The wastegate is ported, fd fuel pump, rb turbo back.
