DT 570 question about hp uprate

[Boathauler]

I have a 2006 I 4400 with a dt570 it is set at 285 hp now and I would like to go to the 330 hp is it worth it or just sell it and look for another truck? I use it to pull boats , but half the time I take my ram3500 with the cummins in it because it pulls way stronger.the boats I pull are between 20 to 30 k including trailer weight

DT570's don't respond well to extra HP (head gaskets and warped heads). Surprised to see a 4400 with a 570, always seem to be 466's. The 570 was not a particularly solid motor, especially if it was worked hard.
