hi everyone I have a question regarding what fuel injectors to run in my FD, I have a proflow fuel rail and the injectors that were in were the wrong cc, I was wondering what cc you guys recommend , I have vmount set up non sequential system, what size should I run? Do I have to be careful about what size the injectors are for I haven’t changed injectors before , any help is appreciated
