im looking for a tuner that will increase my gas mileage and give a little more horespower, or some other way i can increase my trucks power.

 

Where do you live? Get a custom tune. Either locally or through one of the sponsors on the site.

 

Look through a couple of the sponsor links on the right hand side. ----->

Nelson, Blackbear, Wheatley in no particular order. They will increase power, make driveability waaaaaaaaaay better, and might improve mileage if you can keep your foot out of it.
