I have a good customer ordering a new ss trailblazer with all the SLP bells and whissles, does anyone know if he can add a hand held tuner and download flashes to the ecu like you can a stang??? he wants to be able to get some mods done and have it tuned with a drag tune, a street tune and a gas mileage tune. is this possible??? an if it is were is the best place to look?? thanks fellas..
