The AccessPORT has all the functions of the Dash Hawk as well as the ability to reflash and tune the car. Some say I might be biased, but you can simply get the AccessPORT and have all the ability to log your car and reflash for more power as well!

got the dh first.
by installing and monitoring the dh over a period of time lets you get to know how your engine reacts to different loads prior to installing the ap.
