AAA did a study on whether premium fuel is worth it. The standard 3.6 turbo F150 sees a 5.0% increase in mpg and a 2.1% increase in hp. So if a Raptor had a 2.1% increase that would be a 9.45 increase in hp with the standard tune. I’m not sure what happens with the Raptor but the national average for premium fuel is about 22% more than the cost of regular so there is no cost savings. In fact it’s a loss but there is a hp gain. How much hp is hard to say because of the differing tune but perhaps someone with knowledge on tunes and stuff can weigh in.
