You have until 200k or 7 yrs on the lb7. GM extended the injector warranty because there seemed to be some bad batches that made it into our trucks. Just make sure they are still good before you hit 200k. I have 115k on my origional injectors and have had no problems.99385 and counting, nothing wrong yet. Probably won't have any problems until 100,001. Isn't that the way it works?
Did you ask them to put the tech2 on, or ask them to check it out, or does your dealer do it just as a good service tool?just to add, my 02 just made it 65000 miles took it in for the fuel filter recall and they hooked the tech2 up to my truck for low power, guess what, need new injectors lol
