I could lean out the <4k area a bit more, but 2% isn't going to save me.

My car's one of the cars that Vince was talking about earlier (the last '09 mentioned).
To switch over, I waited until I had just under a gallon of 93 in the tank and then topped off on E85, reflashed, and then drove around for 15mins or so to get the mix flowing and began logging. Fuel trims were initially negative and then LTFT drifted back to zero as the E85 mixed and began getting used.
As far as running E85, so far it really seems to take well to it. Idle and normal driving is very smooth, all random knock has disappeared, and it pulls remarkably harder. I was pleasantly surprised.

Well with the 1:1 still in the tank and reverting my MAF tables back to pre-E tune tables, the LT shifted 7.8% + after loading the new layer. So its def doing something, before I had 12-14% +.
I did a couple pulls and with reduced DAL's I am having a REAL hard time getting traction in 3rd lol.. IPW was 9-10ms max and IDC never went over 33% and that was a spike once. I have half a tank of 1:1 in there that will almost be gone by the time I get home. Should be perfect to fill tomorrow afternoon with straight E and then when I head to the dyno, I pass the E fill station again
Dyno will happen on Sat

How are you going to prove it? That might be tricky but it sounds like ZZP found a way to put a pressure fitting right at the HPFP inlet
