Not everyone runs 700+hp trucks.How many on here actually care about mileage in their 700+rwhp trucks? I sure don't.
And when you drive even 40k a year ya mileage counts when diesel is $3.25 a gallon and even just 2mpg increase is around $1000 a year in savings. Doesn't sound like much but if you lost $1000 most would be pissed. Adds up after a few years.
