I've got an 03 LB7 and it is still on the original injectors. Truck has 85k on it. I know there was a recall on the injectors but have not had any problems. Noticing lately motor is sounding different. Have a little bit of white smoke on start up. Mileage is around 15. It has a Hypertech on program B.
How do you know injectors are bad?

thats what my 02 lb7 started to do,and it was injectors,find some one with efi live and have them check the injectors for you.
You can take it to a GM dealer have them do a balance rate test that'll give you some info on the state of the injectors
