I have never have had a tune for E85 but if you are losing any pressure in the fuel line you really are walking the ragged edge and should upgrade the fuel pump. If for whatever reason you end up running the engine lean it will burn something in the combustion chamber and that is expensive. It is always smart to have extra fuel pump capacity to avoid burning up plugs, valves, and pistons. I would run a dual pump if I was you.
