Would it be pointless to use a safc on a stock s4 t2 ecu?
All I have done is a full emissions delete, full 3in exhaust, 720 secondaries, 225 walbro fuel pump. Everythig else is stock. Help me make a good decision. Thx

 

Can somebody answer this

 

I think it would be useful but would not use it without an air/fuel ratio gauge.
