The hottest Ive ever seen was in july on some back to back runs, was 120, but usually around 100 degrees on most runs. this is on just 93.

I dont disagree with you, e85 is better. But all my logs show my demanded fp and actual fp are the same, and inj dc is only 56% at max. if my iats are cool, and theres no KR, then...

Engines do typically run cooler on E85, but E85 does not "reduce" IAT's. This would be a function of the intercooler or meth if you have it, but could be several other variable as to why you buddies car runs hotter.

The concern with running pump gas and high boost is engine knock. As you may already know, E85 has a functional equivalent octane level to 109 fuel. This is protecting your engine from detonation.
