So with stock injectors the car has to be running close to 100% duty cycle to maintain the correct volume of fuel under some conditions. Are the tuners testing the cars at different loads and different rpms to make sure the car isn't running out of injector?

The car isnt running pure E85. Filll up without about 14-15 gallons of 93 and 5 gallons of E85. Regular 93 already has 10% ethanol. The mix gives a cleaner , cooler burn whcih in turn makes the ECU advance timing instead of pulling it on higher boost and high temps thus making more power.
