I changed my ewg spring from a .4bar to a .9 bar spring because you could hear the wastegate/ screamer opening before I hit full boost , I still hit full boost of 1.4 bar. I'm using a avcr to controll boost since I installed the bigger spring the wastegate/screamer opens about a bar and I adjusted the duty lower so I hit 1.4 bar the boost feels stronger now would this need the afr checking? It was mapped to 1.4 and is not boosting any more but it feels as it's pulling more.
