You can compair a piggy back system wiht a standalone. It comes down to your tuner? Can he tune? I wish i could afford haltech i would pic that in a sec.

Also AEM is not comming out wiht a standalone this is a piggy back system. the standalone you would have to convert your throttle body with a cable. Just seem too much work. After all that you might as buy the haltech.
