I’m not sure the difference in the vk56 engine differences from 2012 to 2020. With the 400hp of the 2020 and 317 of the 2012, is it just tuning that are creating the power gains or did they really make internal upgrades to make this happen?
The 2012 is Port Fuel Injected (injectors sitting on a rail in the intake manifold, shooting fuel at the valve when the computer says its open) and the 2020 is a direct fuel injection motor, where only air is delivered via the manifold and the fuel is directly shot into the cylinder. The heads are (obviously) different, as is the tuning in the computer. If you want to make power with the 2012 VK56, you can. Contact Cajun B Pipes and they can start you down that road.
Thanks @busemans I’ve had two titans in the past. I’m thinking of getting another titan or maybe an Armada. I’ve gotten use to having an SUV and have 5x8 trailer and don’t really “need” a truck anymore.
