Yes for my crewcab. They are 18 lb/hr at 3 bar IIRC. Some people have swapped in stock LS1 injectors with a computer reflash for power and mileage gains but I dont understand the whole system well enough to do that with my DD yet. There is an 80+ page thread on GMfullsize specifically about the 7.4L Vortec (L29) but I have only read about 1/3 of the way through it. I am seriously considering doing an exhaust and injector upgrayedd, EGR & cat deletion with a computer reflash but am still hung up on the "not modifying the DD" idea. It deffinately needs new injectors and after burning ~60 gallons of old gas from parts trucks over the last two weeks it will probably need them even more![]()
