I actually don't think it blips the throttle when decelerating on the computer downshift in Manual Mode, and I wish it did. That would make every stop pretty exciting
I wish the 7AT had a Sport mode which would make auto and manual modes more aggressive:
In Auto Sport, upshift at much higher RPMs (redline at 75% throttle). In Auto normal, go into neutral more aggressively (like other, older ATs).
In Manual Sport, downshift rev match for computer downshifts. Not sure how else to make Manual mode more aggressive.
