Default need some performance help

I baught a 95 Cummins. She dont seem to have much low end power. She has 4in. Turbo back stock turbo pushing 30 psi. Idk what done with the plate of AFC if anything it has air dog system . She doesn't push but 5 psi in first or second gear is that normal? He said the injectors were 450cc witch I think is to big. But im wondering what I should do with injector plate AFC ex. I wanna build boost faster I want alot of low end power and some high end but still get good fuel mileage I i drive highway everyday . Where should I start and what exactly what I should do to gain all my power . All input would be great thanks.
