warranty? well... if you have a piggyback type tune, leaving it in and/or having codes that indicate such tunes may make warranty claims related to drivetrain/engine etc a little harder if they're in plain sight. Also depends on the dealership and how much of an arse they want to be about it.

driving dynamics? "improved" is one word that should coem to mind after flashing or installing a tune.. lol
