5.9 Cummins In Ford

Hi there, I have a 5.9 Cummins common rail that Ive swapped into my 2010 Ford F350. Everything seems to be going ok with the swap other than now that the engine is in the ford it feels as if the engines in limp mode. Barely any power and will barely make it up a hill in high gear. Fuel pressure looks good and only makes boost relative to engine speed. (10psi at 1200rpm, will climb up to 20s higher RPM but still weak) Wondering if this has anything to do with there being no dodge transmission anymore as the swap uses the 5R110W. Is there a parameter that holds the engine back since it cant see the old trans?
