2003 Chevy Silverado 2500HD 2WD
So I am looking into getting the SAC 45's (since the SAC00 are no longer available) and I am wondering if I am going to need to upgrade my lift pump for these bigger injectors. The truck is completely stock and it has an EGR so I don't know, if going with bigger injectors, is there is anything I need to add to the list so I don't have components crap out on me down the road. I'm planning on getting the SAC45s through LDS with the master installation kit, new cups and new high pressure fuel rails. And I'm looking at getting EFI Live since I'll definitely need a tune with larger injectors. If anyone has any input on a job like this or advice I would greatly appreciate it. I am a newbie to diesels and this will be a first time experience for me doing injectors. I appreciate you all in advance!
