So I will have a video on this (someday) but preliminary results are that the car is SLIGHTLY more aggressive, however, I now have popping out the exhaust (which I think are the waste gates opening) again between 2nd and 3rd gear. Not. A. Fan.
I didn't have problems with a 1 gallon to 16 mixture. Once I went to 1.5 gallons to 15.5... it threw everything off.
I'd be interested in working with Livernois to see if this is why people are having problems with the winter blends with the 93 tune. It seems the more ethanol in the fuel, the more tune irregularities people will have.
Also, another factor that may attribute to these results, we are seasonably colder than usual. Weather has been 50-58, with relative low humidity (65-70%)... as opposed to when I started the test with 80-90 degrees and high humidity.
