Justin,
I am back to 0,0,0 with the 87 Performance tune. If I run 93 octane the pinging goes away completely and the truck runs great. Of course, the reason I ordered the 87 tunes was to save money at the pump by allowing me to buy regular gas.
I also tried 89 octane and the pinging is much less, but still there.
You have several emails from me on this topic, so please let me know what I should be doing to get a better set of 87 tunes for my truck.

PS. I live in Houston, Texas, so I do not think we get the winterized gas down here.
