And I think you need to understand how the pressure before and after a turbo doesn't change much. How could it (unless you have a wastegate and in that case the turbo isn't lowering pressure, a valve is ahead of the turbo). The exhaust gases pass right through the turbo, as long as the exhaust is the same size as the tube exit there is no change in back pressure. Make the exhaust too large, and you lose back pressure. Too small, you get increased back pressure.
In either case, reductions in power can occur. One from the turbo not spinning as fast, the other from the engine having to work harder to expel exhaust.
A turbo isn't much different than a person blowing on a pinwheel. Blow with your mouth wide open (low pressure) and the wheel moves a little. Blow with your lips closer together (high pressure) and the wheel moves a lot faster.
