Not necessarily the tunes fault, but my ECU is once again inferring a high alcohol percentage which then on the FF tune dorks around with AFR / Timing parameters. I tried a bottle of injector cleaner right before, maybe this caused the issue no way to tell until I refill completely. I'm going to keep resetting the KAM and run codes tomorrow.

Interesting article, I also have noticed my car never liked e85, never, I could only really run e50. I may have lower fuel pressure or weak injectors. Good luck trying to solve at a dealer though.

I had a similar problem before however it was due to a faulty catch can with a monster vacuum leak.
