My brother just purchased a semi-built truck and the compounds had a bunch of exhaust leaks. We tore the compounds off to repair and turns out it has a s475/87/1.25 t4 charger as a primary. Is this sufficient turbine flow on a 6.7? It's a BD kit that was using a 64/71 as a secondary which we are replacing with a 62/68/14.
