Using Scanguage to tshoot codes and to help better monitor driving style and engine situation has saved me enough on fuel to buy the second one.

Follow instruction closely, be patient with updates and registration. Installed canned 87 tune on 2003 Tahoe with good results. Also just changed tires and used it to change tire size. Notice good throttle response and good shift points. Haven't tried 91 tune or modified yet. I like it, plug and play is nice, it is really just a flash tuner but very nice.
