My vr4 is at 14 psi right now and I'm guessing its starting to push the limits on the fuel capabilities. I was thinking about upgrading the fuel injector size to 550cc. Any opinions or recommendations would help. Thanks
360cc if you haven't upgraded your turbo's you will not pust past the limits of them. Unless they're bad.
