More Air, Stock Fuel, Big Power

In the past, we’ve shown you how tuning alone can bring a ’15-present 6.7L Power Stroke up to speed in a hurry. As in, a 540hp and 1,100 lb-ft at the wheels “hurry.” But with everyone and their brother rolling around in tuned, 540hp late-model Super Duty, some of us want a little something extra to stay ahead of the curve. Given the untapped potential that exists in the factory ’15-newer injection system, bringing more air into the equation can yield impressive results. A 63- to 64-mm VGT upgrade on its own can add 50-60 hp on stock-fuel 6.7L
