I doubt If I'll do anything. But if I do I'm specifically looking at 2014 F-150 with 5.0L V-8, 3.55 gears. I don't feel it is short on performance, but if I can get a little more HP, torque without losing fuel mileage I might consider it later.

Just trying to make sure I fully understand the concept before doing anything.

Most people don't really want the truth.

They just want constant reassurance that what they believe is the truth.
