Default Fuel Delivery

During the initial ‘post’ upgrade pull, the injectors maxed out and she ran out of fuel at 4700 RPMs. Fuel pump is good - but we found that the regulator can’t keep up when the boost starts to climb. Swapping in 1:1 Boost Referenced Regulator which ‘should’ keep the LS9 fed and happy!

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.
