Going to try getting some better quality fuel in the car tomorrow and see how she does. Thinking of adding 101 my current 91 to get 93. Does that seem like a good idea?
If you need someone to test flow and clean you injectors, let me know. I've been cleaning/servicing N54 injectors for a few years now. Not all of them can be saved if they are leaking really bad, but lots of times bad spray patterns, and small leaks can be fixed. Shoot me an email at iqraceworks@gmail.com and I can get you more info.

Hello everyone. Today I went to a new gas station. And I got 91 but added 2 gallons of e85 to try to get closer to a 93.
In my log, my timing corrections seem to be nearly gone. I dont really know what I am looking at. So if someone could take a look and let me know what you think that’d be awesome. I think it’s headed it in the right direction.
What’s up with the throttle cut?

Wow, that's one of the worst cases of bad fuel I've ever seen but it looks like it's cleaning up nicely for you.

FYI, I think what the other guy meant when he said to make sure you get a good clean log is simply to keep your foot to the floor til it's done, the throttle position decreases slightly in both but no big deal, it's still ~WOT

I would keep an eye on your injectors as they are problematic and can cause similar issues but your new log looks tons better. Keep gassing up here and see how it goes!
