Me and a friend (Lb7Chevy4x4) did injectors in his truck this weekend and found some interesting things. 3 out of the 8 injectors we pulled out were completely clogged/plugged/fucked. the other 5 weren't much better. We also discovered a giant hole in his drivers side IC pipe. After the install was over and we were doin a test drive and logging some data, we checked rail pressure. the truck wanted 23,000psi and was only making 6,000psi. So this truck was hauling 20,000lbs weekly with terrible rotten injectors, a giant hole in the ic pipe, and an extremely weak cp3.
