The owner of the company I work for has the same truck 05 but a long bed. He just put compounds on his and he has 100hp injectors. Truck runs great. Egts are never a problem. He also has built tranny
He also had a 2023 6.7 dually and he said it feels like it has more power still than his modded 05 until it detunes because of egts.
Not really looking to mod this. Just sort a few things I don’t like and use it as a comfy tow rig/camping vehicle.
