At the time of the dyno run and up until a few months ago I was running straight 93 octane pump gas (E10 - 10% ethanol). Now I run ethanol-free 93 octane gasoline (aka recreational fuel). Can't be sure if it makes much difference, though. Because of the heat, humidity, and DRs my ETs have been slower overall.
If I can get someone to follow me to the track with my truck next visit I'll try running out all my pure gas, cool down, then give it a slurp of the E10 and see what happens on the same day. Pure gas should be better because it takes higher compression (more boost), more fuel volume, and tuning to take advantage of the ethanol. Otherwise it just dilutes the gas.
