I ordered what I was led to believe were stock injectors for my California truck. What I received were AA's. My cores were AB's. This issue was not caught in time and installed in truck. Truck runs great cold but has cavitation apon throttle release and no response for the first inch of pedal then goes to 1500-1800 rpm. Is there a chip to compensate for the AA injectors? Dieselogic will not take back these AA's. I would appreciate any help, thanks.
