I would say yes. Never measured but when I let off at the end of the track it sure sounded like it. I was making mid sixes with it at 14.5 or so psi with 383 cubic inches. I really don't think there was much left, if any. It was my brother's turbo first and he made 688 iirc with it on 326 ci at 20 something pounds, so I know my bigger cubes were taxing that turbo on the track. Stupid fun turbo on the street in a 2 ton truck, I'll tell you that though. Almost instant boost.
