I may be going out on a limb, but I feel the car runs better with this E25 blend in 90 degree weather than in 70 degree weather w/ 93 octane. I can drop it into 3rd gear @ 50mph, go WOT, and the car feels like it's riding the proper ignition curve vs. having a flat feeling (ignition retard) when accelerating at WOT.

I'll snag the BT tool tonight to log ignition timing & fuel trim(s) to see if I need to adjust the blend.
