Long story short, I thought I was running an 87 octane tune on my 2011 Silverado 1500 with the 5.3L and learned it was a 93 octane tune (canned Diablosport).
Over the past two months, there have been a handful of WOT runs and the truck has towed 5-6k lbs a few times.
Should I be concerned that I hurt the engine?
