Help me understand...
Since the dealer replaced my '05 6.0 PSD turbo I have noticed a significant increase in mileage. I went from 11/13 to 15/18 (city/highway). Dealer told me they coud find nothing wrong with the turbo but I've got my torque back under load and the increase in mileage.... So... my question is this: could a "bad" turbo have such an adverse effect on my mileage? The obvious answer is it must have but I'm looking more for a "Yes, that makes sense" (or no it doesn't) kind of response. TIA.
