I've heard maintaining a .48 or .49 driving hard is within normal levels. that's not correct? Definitely I agree we would benefit from 93 as this tune was done on a car running on 93Maintaining knock control levels near .49 with a tune such as TSP1 should not be expected when using 91 octane.
Blending a small amount of E85 in will increase your octane level, decrease your knock control reading (due to less knock), and give back the power you lost by having a knock control level of .49.
If you already maintain a knock control level of .49, this would not help you.
