Does anyone know what the manufactures maximum pressure rating is on the Duramax fuel injectors? I know they are somewhat a week link on the Duramax engine. I have read that the stock pressures are about 22,000 to 23,000 psi. One particular performance program (DURAMAXIZER)increases it to about 26,000psi at maximum setting. This is about a 15% increase. I'm certain that GM designed the injectors to handle pressures greater than there operating pressure.


Does anyone know what that is?


Any and all feedback welcome.
