Where did you get the tune done?
Do they have a 94 octane tune and 91 octane version?

I used a local tuner that is very good (finish line performance) - it was a 6-8 month wait to get in and I had to bring the whole van. He adjusted parameters and test drove it around to assess the impact of the changes. I asked him about multiple tunes, but he basically said it wasn't worth it, just use the 91 octane when towing. We had 87 in the tank when he tuned it (no trailer) and couldn't get it to ping under load. He said I could try the 87 and see if it pings, but I didn't want to take the risk.
