Has everyone with these manifolds seen a decrease in boost levels?
you flow more air so you make the same or more power on less boost. it makes it more efficient so less boost does not mean less power. you have more airflow with less heat because of the lower restriction and that is a good thing. more boost with more heat from more restrictions=less power.
