Be careful bumping up the HP and Torque on the Cummins. The diesels have been de-tuned to keep the transmition alive. The ETH is reportedly going to come out first only on the manual because the current Auto can't handle the additional power and torque. The rumors are that Dodge will get the new Allison automatic (sharing it with GM), which is an excellent automatic that will allow much more power/torque output from the Cummins. So if you change the computer chip to increase output, you might be jeopardizing your tranny.
