From TCM manual.  For turbocharged engines...."An integral anero= id valve functions to increase pump output pressure during high manifold pr= essure operation."  If the upper deck reference line was leaking and suppling the pump with a low value, the fuel rate wou= ld be reduced. However, both banks would be affected. I don't know what wou= ld affect just one side. You also would see the reduced WOT fuel flow assum= ing you have fuel flow displayed.
