Going lean most likely because your fuel injectors are too big. 60#?
Just to be sure could you list all your engine mods? Do you have an intercooler, hot cam?

Fuel filter
If any of these conversion techniques are used, especially in older vehicles in which there may be rust or other residue present in the fuel tank, it may be necessary additionally to replace the fuel filter within 400 to 600 miles, as ethanol has a tendency to release any trapped rust or gasoline fuel gum or residue, which can cause the fuel filter to become blocked. Once replaced, life expectancy of the new fuel filter should be normal, barring an exceptionally dirty gas tank or fuel system.
Running E85 in a vehicle can actually improve fuel efficiency if the fuel delivery system was especially clogged up. This improvement remains if the vehicle is returned to operation on gasoline only.
