I'm helping a friend tune his truck which neither of us have ever done before. We used a tune from the tune repository. https://www.hptuners.com/customers/t...ownload&id=438 (this is the tune we used). The truck is running good, however it is running rich on bank 1 and 2. I have attached the scan from his drive after adding the tune. Any recommendations would be much appreciated since we have no clue what we're doing.
