Looking to get an e85 tune on a Lincoln LS. Only mods are CAI and mufflers. Do you think that even though the car is relatively stock, that I would need more fuel flow and would need to upgrade the 19lb injectors and fuel pump? If so, I have found 24lb injectors for very cheap, and I'm looking into the pump. Also, would I have any issues with the E85 creating problems for the fuel system? As in, would it wreak havoc on my fuel lines, o-rings, etc? I have an 04 cobra so I know that those cars have handled e85 just fine with only upgraded injectors/pumps in a returnless system, but could I assume the same with an 06 Lincoln LS? Should I worry about the stock fuel lines, etc?
