The GReddy e-Manage is kind of an over glorified piggyback. With some addons it can be pretty versatile but I'm kind of indifferent about it. It's still essentially a piggyback. However for a relatively mild n/a setup it should do ya just fine and can run turbos with reasonable success as well. It's not as versatile as an AEM but if your guy says he can get it to work with your setup I would at least consider it.
