The RPM is much better than the performer or P4B Q jet flange, Especially ported, you will gain 10hp up top but lose 10ft lbs down low with a 1" open spacer, a 1" open spacer will net you your best et's and you will be right there with a T2 that is untill the T2 is fully ported with a 1" open spacer fwiw

About Us

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
