So how critical is the change in pump E85 if we plan for the E50 blend? Pump can vary on E% depending on time of year and each batch. Do i really need to test tube each fill up or is there enough cushion in the tune of the E% is off a few points? I really don't wanna test tube each fill up, that's a pain in the ass!

If i stick with the correct E85 gallons per fill up I should be fine if I wanna run the E50 blend tune? If i have to test each batch of E85 i'll most likely pay for bigger injectors so I don't have to F with it!

Please post your experience.
