Ok so some of us know how to roughly calculate injector and their HP potential by taking injector size X 16. Now I read above response, injector being too big! I thought one could slightly oversize injectors and just adjust fuel pressure lower to increase flow or via injectors pulse via programming is this not the case?

Adjusting fuel pressure always has been and always will be a band-aid approach to altering fuel delivery. Running too large of an injector for a given application will kill idle and part throttle driveability. The larger the injector, the less efficient it is at low/no load and rpm. Also, your rule of thumb injector size X 16 is quite a bit off as well, on the high side. Using that formula would end up leading you to believe that a 36lb injector is sufficient for 576hp. In reality they are good up to about 450.
