I don’t have dyno numbers, sorry.
The tune is actually four different tunes with a hand held controller that plugs into the OBD port. I have:
93 octane performance
91 octane performance
87 octane
Fuel Economy
Those are my four choices.
I use the car as a cross-country vacation car. I drive to Colorado a lot and can only get 91 octane there.
Also, around my home area, 87 octane is all you can get in some places.
I figured this has me covered for how I use the car.
The goal was to get the air/fuel ratios right with my deleted secondary cats.
The “aggressive” tunes maximize power for that given octane fuel. It works.
The midrange bump is impressive.
Cheers.

10/10th you can get 100 octane 1/4 mile south off kipling on Alameda Mobile gas station in Lakewood, Colorado.
4 gallons of 100 octane and the rest in 91 will get you to 93 octane
91 X 14 (Ga) = 1274
100X4 (Ga) = 400 1274 X 400 = 93 Oct
Try this formula. I believe it was posted by H2OSkier a month or so ago.
1. (Octane of fuel #1) X (# of gallons of fuel #1) = X
2. (Octane of fuel #2) X (# of gallons of fuel #2) = Y
3. X + Y = Z
4. Dividing Z by the total number of gallons of both fuels gives you your total octane number.
