If you are looking for more heat, then yes, it will give you that, BUT, that is it.
If you are looking for better MPG - forget it, you can get better MPG by keeping the truck light, no lifts, nor oversize tires, speed under 60, and treat the go pedal like an eggshell.
If your truck gets checked for emissions with this tstat, do not be surprised if you are not passed on the emissions test.
Hopes this helps,
