his stock injectors are deffinitly maxing out on 8psi. the fpr and pump i know can hang in there, idk with 8psi but anything less than that and they'll hang in but its a very good idea to upgrade!
sorry gocartracer i shouldn't have lashed out like that but i didn't see the guy post his setup yet and u gotta see what their setup is before you can say whats safe or not. you know what i mean.
