depends on the turbo. you are making a very common turbo noob mistake. 7 psi on turbo A is nothing compared to 7psi on turbo B. for example on my Supra at 15psi i was making 450HP on my old 62-1 turbo. when i upgraded it to a T72 at the same boost level i was making 575HP.

now to answer your questions, YES you MUST upgrade your injectors. a very simple turbo system is use the stock 3S-GTE turbo and manifold, supra 310 injectors and the 3S-GTE MAP sensor.
