TomeyGun you are correct about there being more power off of the line; I cannot say where I got the info but there were changes made to the boost control on the wastegate; also look under the transmission anything different??? Lets say something should be missing... Also should be something missing under the hood... LLet me know what you find as we do not have any diesels on the lot yet, my truck is scheduled for the 22nd Oo. to be shipped.
