pulling the battery resets the learned data in your computer, but your computer still has the base parameters that don't change. The learned (realtime) data only affects so many tables and changes only so much. Any "auto tuning" would be very small adjustments to keep your car in nominal ranges, and wouldn't really improve your power substantially

I didn't mention etunes and brushups because open source tuning allows you to send maps to/from a tuner for etunes as well, and it's not really any more difficult if you know your way around a computer. But

With an 07+ you also have Si drive, which your tuner can set to different levels of performance to aid in economy. My tuner set my modes to 9, 16, and 19psi in i, S, and S#, along with dulling the throttle response in "i" and sharpening the response in S#.
