I have an 05 lly and was wondering which one to get, the efi live scanner or tuner. Not really interested in tuning, but I do want to measure as much of the fuel system as possible, such as the fuel pressure regulator, injector pump, fuel rails and injectors. Will the scanner do the job, the tuner, both or none? any help would be appreciated.
I have a 2005 chevy silverado 2500hd with lly, no mods.
