Switching between map 1 and map 2 on my tune switches between AFR targets of mid-12s and high 12s. The leaner the mixture, the slower my car feels. Going to stock map, which leans out to 13s and 14s and the car feels notably worse. All on 93 octane in NYC.
I'm a little confused why you'd call a lean mixture as more aggressive when it feels worse driving.
