tuner is you best option, for all the reasons stated, like puling codes and stuff. you can have multiple tunes on a chip, and have a switch installed that can allow you to change it, but if you can use a hand held tuner, why have the chip??
you can get multiple tunes, depending on how you drive. if i were you, i'd get an economy tune that runs on regular gas, and might as well get a 93 tune for when you want to run premium.
