Just returned back from the dealership, a good experience. They have ordered replacement injectors (all 8) and concurred the balance findings, although #6 was showing a good reading, number 3 took its place when put in gear. They have to be ordered, 1.5 - 2 weeks ETA, no problem. The tech had mentioned the replacements are rebuilt, which I could care less about, and they are also redesigned internally as far as the "rebuild" goes. He also stated he was very surprised they were able to reach 100K. There were no gripes about intake, exhaust, a previous tune, lift, etc. It went very nicely. I feel for others having a hard time getting things handled smoothly.
