Hi my name is***** will be glad to help. First confirm those temps are accurate by checking the actual temps with a digital temp reader at the manifold. You can get the temp reader at most hardware stores. If the pyro is in fact reading correctly, check for leaks or restrictions in your charge air cooler and intake piping. If okay also check the temps between cylinders for a hot or cold cylinder out of line with the rest indicating a potential injector problem. If all reads normal you could have a faulty sensor, harness, or gauge. Let me know
