Mike could this be a result of not enough modifications or octane to run Map7? I thought it might be safe to run Map 7 (race map) for just a couple of dyno runs. I actually was running 93 octane with octane booster. I know, probably dumb, what can I say, wanted to see high numbers. Could that be a reason that I am too lean? The air to fuel ratio graph drops off at 5100 rpm it isnt consistent.
