Guys....this is 18.7psi in the MIDRANGE, not up top, and still below the turbos efficiency range at the specified 3000-4000 rpm. I'm still running normal tapper up top for a piggy, which does overdrive the turbos past efficiency.
Nonetheless, this was only an experiment to see if my car is ok with it.
