So a while back I got an E30prx tune from MPT and I have to say I was pretty impressed with the power gains. Today I went to my usual gas stations which is normally e75 in the winter so I filled up with 11 gallons of ethanol and 25gal of 93 well after filling up I realized it wasn't E75 but was E65 so that puts me at E27. Is this anything I should be concerned with?

no, just monitor it........... when you get a few miles in it, add a couple of gallons, you will be fine

I personally like to be E35 if I am running the E30 tune

I encourage you to reach out to MPT and maybe request one of their tuners respond to your question. Questions like, is MY tune meant for E30 and below, E30-E40, E30-E50? As I went from 93, to blend, to stronger blend, and then to E85 different tuners said different things.

My EZ lynk and tuning would display the E content but would sometimes fluctuate greatly and I was not setup for E85. I have went back to a SCT tuner and I don't know how to see the E content but I am also setup for E85 now.

I hope this helps you out.
