I can't see anything working that won't choke the life out of it. My 6.5 had pollution control devices to include reducing fuel to the injectors. I pulled the EGR manifold out, and put different resistor in the PMD or what you would call a fuel control device plus my super secret fuel additive and got 18% better mileage.


I think the only ones going to be hurt are the California VW owners, they got the toughest epa out there.
