I recently took off the chin spoiler on my truck to see how much it affected my mpg during my trip from southern California to Lake Tahoe and back. I was curious if any of you have seen any major differences to your fuel economy when you added/removed your chin spoiler. I'll update my findings when I complete my trip.

 

i think its called an air dam

 

And or valance.

 

And or gas mileage increaser.

 

It's dam(n) ugly... I've also thought about removing it, but haven't gotten around to it yet.

 

....removed.

Taking a long trip over the holidays...so we'll see how it affects MPG.

Northlight

 

Just took mine off looks so much better with out it.

 

I actually took mine off today as well. I'm very interested to see if anyone has different MPG's with and without.

 

Wind Tunnel Testing......
I hate to inform you but it there for a reason.
Albeit minor in some minds, its actually part of the whole Aero package designed in tunnel testing to get the most MPG they can to please the Gooberment.

Just Sayin.

 

X2 i was thinking that same thing.
