Are you actually measuring your ethanol content in the gas or just filling up with 2 parts of E85 to 1 part of 91 at the pump?
No, I haven't measured the ethanol content. My tune isn't on the ragged edge at all, so even if the mix was gas heavy it would just be rich with a little less octane. Nothing too dangerous as far as I am concerned. I run 1 part e85 to 1 part 91.

As mentioned above part of my fuel is still gasoline, so the injectors go a little further. Highest I have seen is 89% IDC.
I tried pushing it a little more tonight into the 22psi range, but it was cutting out and sort of misfiring. My wideband is on the fritz (stuck at 14.7 for some reason), so I have no fueling feedback. I do know my VE table is really high in the boost areas I haven't (til tonight) ventured into, so it may be just really rich. Either that or the plug gap is too wide. If I can get that figured out, I may bring it to the dyno day on Friday and see what she does then. If not, I will strap the Geo down and see how high into the double digits it'll go
