Yes, Ford's 6.0 Power Stroke had a few teething problems when first introduced in '03. Fast-forward three short years, and the '06 model year is everything that the first run should have been: powerful, and most importantly, reliable. A Superchips power programmer takes advantage of the big-time performance potential that lies within the new-generation turbodiesel engines. The only other mod is a free-flowing aFe intake. Even with the minimal modifications, the Power Stroke can easily smoke the 38-inch Dick Cepeks, as a certain editor's right foot can attest.
