I think an ISX 400 can go up to 500 with an ECM flash alone provided the transmission is rated for additional torque.

On a side note I wouldn't pay Cummins, Cat or any other dealer/engine mfg to uprate an engine. Been down that disappointing road countless times. Aftermarket is by far the best bang for the buck for both HP or fuel mileage.
