Hello everyone, awhile back I bought some edge jammer nozzles and havnt done anything with them yet because im pretty sure that when I am to install them that I will have to set the pop off pressure. Can anyone tell me how or if I can to this on my own or if I have to pay someone to do it.

Well as for putting the injectors together yes you could do it yourself... But as for doing it right your going to need to take the injectors into a shop and have them pop tested and set properly.

Here is a good idea what injector looks like and how it assembles...
