Did a Roar Pedal just boost my MPGs?

[PapaBear351]

I'm about a month into owning this 2025 XLT with the 2.3, and one of my first impressions was "dang, Sport mode sure makes the throttle way more responsive!" but I also wasn't wild about hanging in gears longer before shifting. So spend a little time on the interwebs and learn that lots of people feel the same way, and there are products out there to address my specific gripe. I decided to give Roar Pedal a whirl.

Installation took all of about 47 seconds (because I didn't feel the little tab on the back of the plug right away--otherwise it would've been quicker).

Here's what seems weird... I've spent three days driving around with the Roar Pedal on Sport 5, and it's been amazing. Snappier throttle response but otherwise drives just like it did before. But with three days' worth of stop-and-go, running around town kind of driving, my trip odometer screen says my MPG has gone up by 2.9 MPG.

I was a little concerned that this might cost me fuel economy, similar to driving with a little more of a lead foot, but apparently it's having the opposite effect.

Maybe that's by design and how it's supposed to work. Maybe the atmospheric conditions aligned perfectly with Mercury in retrograde. IDK, but I'm not mad about it.

Maybe you just got a batch of really good gas

Your driving habits might have changed slightly since you’re aware of the new equipment. Recommend revisiting it in a couple weeks.

Can’t think of another reason unless your Ranger defies physics!

The only thing a roar pedal does is change the throttle position relative to where the computer thinks it is at. That is it.

It is nothing else other than making the throttle touchier.

Because someone becomes trained or accustomed to moving their foot a certain amount for a certain response, they think in their heads the vehicle became more responsive. Your tune is still exactly the same. The MPG and mixture is the same. Spark timing and everything else is the same. The idle position is still idle position, WOT is still just WOT. The stuff between idle and WOT in the throttle range just moved to a new position.
