Based on other dyno's I've seen, no the A/F is not normal. The values are about the same, but the consistency and linearity of the line are substantially different for yours. Here is an L99 Dyno from 5gen.org, before and after a tune (again NOT suggesting a tune)

Keep in mind, different dyno (well, both dynojet, but physically different..lol), different weather and they use the SAE correction factor, so the HP values are not directly comparable. What wont change is the shape of the line. As you can see, the A/F plot, even before the tune is very linear and smooth.
