Just wondering... I happen to talk with someone I know last night. He has a 05 Dmax. In talking to him.. it's been back to the stealer a couple of times. However he said one time the tech reprogrammed his truck with a GM supplied 370 HP and 485??? torque.. ( I forget what the Torque numbers were) .. Stated that it's an available download from GM, changing the truck from 310 to 370. Any one else hear of it?
