Another turbo ?
Ok, we got the air/fuel ratio installed and I'm getting a reading of 11.2 or so on the O2. I'm assuming this means the car is too lean? I have heard we were looking for mid 12's on this reading. Two part question, am I correct that it is too lean and do I just adjust fuel pressure for this or fuel and timing? This is a 4 cylinder turbo ford combo stocker.
