Here's the DA data for this morning:

Later today when it's 80F the air density will go down to 85% so that won't help
Try to run your current fuel way down and then fill up with the good stuff. Run it through until you are about that 3 gallon mark. The computer will need a few miles of the good fuel to adjust anyway. Love to see that air temp below 60 degrees. The turbo will respond. My plan is to do my runs in the 45-50 degree mark in the spring. Look in the manual and it will state you can run your tires at max pressure with speeds over 100mph. As long as you hook up, that rolling resistance will be reduced at max pressure. Try folding your side mirrors in on a few runs. Your active grill shutter position will most certainly make a difference.
This is a fun project. I love to do this kind of stuff.
