I'll admit some cases with diesels could benefit powerwise, but probably not most of us.

I'd almost like to call bs with the mileage. How many times do you hammer the crap out of it and loose the mileage you gain in other situations.
So your just saying that a gas motor NEEDS the power and someone with a diesel WANTS the power.? To me more power is the same however you look at it, its not needed but can make driving more enjoyable/better.

I have yet to get below 15 since with my new tunes, no long hauls just boats and such. Before the best i was getting was 15 and averaged 13 with any city of towing.
