RE: Dyno Chart Help!
So the red line is my air fuel? or is it the green one? The shop owner was telling me that its the green one, and its off the charts rich.

When I tune it I will put two widebands directly into each bank of the exhaust and properly measure a/f.
Your a/f actually looks to be way too lean for a blower car. It looks to be 13:1 if their wideband is working right, it should be 12:1 or richer at high RPM.
