Default Am I too lean, dyno sheet included

I had my car dynoed and tuned a while ago, maybe 9 months ago, and I never really paid much attention to the a/f as I trusted the guy who dynoed it (Pete at Performance Dyno)

Anyways, the chart below is a comparison to a stock, then an 89 tune with a JLT. IDK if the tuned a/f ratio, right around 13.0-13.1 is too lean. I am looking for a few words of advice

It is pretty flat. This guy definitely knows his stuff on tuning mustangs.

Looks very good. It should average 12.8 or 12.9

Thanks guys, just wanted to get some reassurance.



Just for giggles, here is a dyno of my dads car and my own. Any guess what it is?
