If that unlikely scenario turns out to be true, I think you should request scheduling another set of pulls with AFR - and they should either be free or steeply discounted. Hooleyboy speaks very highly of the shop and owner, so I doubt this would be a problem.
The alternative would be to install a datalogging solution with a wideband - this would likely be at least a couple hundred bucks, but gives you immensely more information both now and into the future.

Here is an old pic of my air fuel back in the day. Generally it should kinda look like this. Its ok if you are a bit lean at the beginning of the pull but it should come down into the 12's

You should absolutely be able to know the resultant AFR's from your custom dyno tune - the data existed when the car was tuned - I'm actually somewhat surprised it wasn't printed on your graph - but sometimes it is, and sometimes it isn't. Dyno-Comp should have the data from your pulls stored - if they weren't given to you, and Dyno-Comp's computer has since crashed and the data is lost... well that would just be Murphy's Law, wouldn't it?

I need to scan my most recent ones and post them. I was getting ready to package them off and send to Jerry with my ECU but I'll get a pic first for comparison. I had a brain fart and was equating higher number = rich, lower number = lean. Bassackwards....

Post up your graphs, Remember this is a pic of a MAF A/F. MAP A/F can look a bit different in the beginning of the run but they all should come down to the same area even if your in the 11's slightly thats ok too. Personally I would rather be a tough on the fat side then the lean side as long as its not pig rich.
