Right now my car has an aeromotive 13202 regulator. When I go from the footbrake to wide open on the trans brake, the car goes super lean and tries to die. I am thinking i need to switch to the 13212 regulator to fix the problem. We have tried adjusting the base fuel pressure to correct it, but it doesn't seem to help. I am thinking that the 4 port design just takes too long to respond with the belt driven fuel pump. What are your guys' opinions?
