If he is just wanting stock injectors it doesn't matter where he gets them as long as they're new Bosch injectors with new stock nozzles they will be the same. The only thing being balanced by DDP is the honing done to the nozzles for added hp, and they are not the only ones who truly do that.The only truly balanced injectors are DDP (dynomite diesel) you get what you pay for they actuality will balance a set for you. several sizes available I put the 50hp+ in a month ago nice! Dodge tried twice they use junk!
If you need to you can talk to the guy that does the setup.
