Have a 1991 Case IH 9270 with 855 cummins rated at 335 HP. Would like to turn it up a bit, maybe to 365. Anyone know how, or maybe a reason why not to? I think the only difference between a 9270 and a 9280 was the fuel setting but I am not certain. There maybe more differences between the two engines than the fuel setting. Maybe someone can set me straight on that. Thanks in advance for any help.
