hot pipe is the line from turbo outlet to IC. You are reading manifold pressure with your gauge and referencing a different pressure for the turbo. If you want a correct boost reading hook up your gauge to the same place as your boost controller.

Ok your turbo is making 10 psi.... but only 7 psi is hitting the manifold. The manifold pressure is always lower than the turbo pressure. Try setting your boost controller to stock or just simply turn it off now take a reading.... the stock turbo goes to 7 psi which is normally around 5psi manifold pressure.
