Hi, what is a good brand of injectors for a 07 6.0 sierra 1500. Have done a dod delete and stage 2 cam. I see so many different injectors online that range from $40 for 8 to $500+ for 8 injectors. I know the cheaper are most likely cheap China stuff or remanufactured. I don't think I need to upgrade to a bigger injector, just a better injector then what it has would be nice. Actually it's a friend's truck he is insisting on replacing them. Thinking I should go with factory injectors. What do you guys think?
Any help would be great. Thanks
