Stock intake manifold or "greddy" intake manifold? If it's aftermarket, going back to the stock intake manifold will pick up more bottom end and mid range. No need for a different intake manifold below 500hp.
Are you running an external wastegate or internal? If internal still, going to an external gate can increase your low end torque and top end power too.
I'd look into going to a 3" exhaust also.
All these things could pick up power without raising boost pressure, at least initially. Just making the setup more efficient. I wouldn't worry about head gasket and studs below 400hp unless you plan on overheating it lol.
