[QUOTE="AuroraGirl, post: 28747, member: 9417"] A detuned version which means longer fleet service and also shores up the CAFE mpg Ratings in bulk. The option also gives room to charge for the upgrade vs a standard power plant. With regards to fleet sales, 1 mpg over half the sold cars meant you could have that many more trucks with a 5.7 instead of a 5.0 and not hurt the EPA credits [/QUOTE]
