I wanted to see if anyone has experienced this before... 2010 Camaro that we just finished putting a Cam, Heads and a Procharger on. Customer had installed a ZL1 fuel pump. Started running the car and was loosing fuel pressure but the fuel pressure would just drop right out. Goes from 60 to 37 in a split second but then starts to come back. Looked into it and the customer did not install the ZL1 fuel pump control module. So we put the ADM controller in and no change. I am at a loss. Logged the Fuel Pump Trims and its only coming back because the Short term trim is adding to it. I have included the log. The car is on 93 octane and at the point where it happens its only making 402hp to the tires and a little over two pounds of boost.

Thanks
