In this particular dyno the HP peaks inbetween the red arrows I drew. At the same time the HP peaked the turbo was atleast holding 17psi. You can see it right here. Any hp/tq/psi reading within the red box is realistically a waste because the HP and TQ takes a dive from there. Typically thats when people shift, when the power drops. All platforms are going to have different torque curves. The difference between a twinscroll TQ curve and a single scroll TQ is huge
