Currently in my 2.5 work Stock puller. They are bosch motorsports 5.9 injectors and work in all common rail 5.9's. (Currently being run in my 04 with 6.7 swap) nice street manors with good tuning (no haze going down highway) , but fuel very nicely when needed. Injectors maybe have 5,000 miles. $2200 plus cores. Have flow sheets.
