I'm a new owner to an 08 quad cab that's stock with 168,000 I know the lb7 which was my previous truck had issues but I have been told they have been corrected and was just wondering what the differences were between the two sets of injectors?

 

I'm a new dmax owner myself. I don't know the answer but you might try duramaxforum.com. Hate to do that but there are a bunch more helps over there. Bombers are starting to step up to the pump on the dmax but 2 days 90 some views and not 1 response? good luck bud.
