I have a new Rick's Tank with pump, new corvette filter regulator. I even pulled the injectors and cleaned them (they're the L59 flex injectors). The engine/injectors only have 400miles on them.
I'm starting to run out of possible causes...
The computer came out of the vehicle that had those injectors right? If you have flex fuel injectors and a computer for a non flex fuel engine then your injector duty cycles are probably too high, those injectors flow more than the standard injectors.

I believe that they were from the same vehicle, but wouldn't put my hand in the fire to prove it! Can I verify using HP tuner? I checked the stoich in HP tuners and it ranged from 14.60 at 0% to 9.00 at 100%. This is the ethanol table isn't it? So I think it's the right pcm...

I am not too familiar with an e85 but its possible. It should still idle though. Do you know the flow rate of the injectors? I would start with the IFR table.
