LB7 with 40 engine codes
So the previous owner is the one who took it to the shop and had injectors and egr delete done (showed me the receipt and invoices). He paid 5600 for the job just to have the same issue afterwards. I tried calling them to see if they would still warranty them and they hung up on me. 🤣 He then... -

Shop bought the injectors, all they told me was they were Bosch remans. As far as reputable I'd say the results speak for themselves considering it sat in there for 6 months 🤣 -

A/C was off, is there a link to the process to check the harness to the injector? I appreciate all of your help, I'm dumb when it comes to wiring -

It was an egr delete kit, shop did the delete. As far as tuning I'd have to ask the previous owner but I don't believe so. Was considering buying the efi live for it. -
