As I understand it these will plug directly into the port under the dash and work without installing under the hood? this is on a 02 dmax, and if it works this way, does it leave a foot print in the computer?

Yes, it does leave a footprint. It will reflash the ECU each time you change levels.

Yes, that is correct as long as you get the Evolution CS or Evolution CTS. The Juice/Attitude CS and CTS plug in underneath the hood. If Gm wants to find out you have had something to enhance the performance on your truck, they can. However, as long as you dont give them a reason, most are very cool about mods.

Thanks guys, I really appreciate your responses, I have an 02 lb7, i'm gonna be pulling 6500 lb trlrs, I guess my question is "your recomendation"?

EDGE CTS is great and has worked for me. You get guages plus more power from the tunes.
