I've been looking at some other dyno graphs and noticed that the a/f ratio on the chart is usually pretty level. I looked at mine and it gradually moves to 11.7. It has a steady decline as the rpms go up. Is that normal or should I start looking into something? It still has the stock fpr and fuel pump to my knowledge.
