Going turbo soon and I just got a vafc for a good price but would like to know is it a good idea to use for tuning. I was going to purchase a Zeitronix wideband w/display since it read boost, air/fuel,egt and this would elimante me getting gauges. But will the vafc be just as good if i do tune with it, I will get gauges for the vafc though. Hope I make sense . Thanks
