    Default Fuel Problem COS3 E40

    We Are having a problem with a 06 GTO going lean for some odd reason and we are having trouble finding out why its doing it....the car is a 6.0 stock bottem end with ETP LS1 Heads,Cam,APS Twin Fuel Pump,60LB injectors,Aeromotive aeromotive regulator and a F1 A Procharger.

    We was making about 5 PSI at 5800 and everything was fine so we changed the pully to make some more boost and now whenever we hit about 5000-5200 rpm no matter how high we make the boost ve numbers it will allways go lean in the same spot

    Could someone please take a look the file and see if we are over looking something?

    Thanks ,Bill
