my tuner is going to bas tune with standard premium, then pump it out and put in E85 and check tune. Then make sure flex tables are optimum for the sensor and adjust as necessary. Does this make sense.

Sorry the images are sideways, on my phone. Car made much more than expected! Now for some twin turbo action (I wish)

Is there a physical sensor in the tunes that have virtual sensor enabled?
If you look in the tune on the drop down menu for Flex sensor, there is an option for Sensor and Virtual. The Diag section also does not enable a physical sensor.
My understanding is that Virtual uses the fuel trims to find the right cell in the stoich table and does not use a sensor.
This is exactly what my 2015 2500HD 6.0L does as well as my old 2011 1500. I will have to check one of the 2014 1500 5.3 DI tunes I have.

Did you run E85 in your 2011 Silverado 1500? Was it a 5.3 or 6.2?
