Has anyone used a Jet Programmer and has it helped with power or gas mileage?

I got this as a gift and dont know if I want to sell it or hook it up. I was debating on selling it and putting in a K&N filter.

I have never been exposed to any of the programmers so quite frankly I dont know what exactly to expect or what it will do. Although I know it can adjust my speedometer and get that leveled out which would be nice.

Any info or suggestions would be nice. I am not looking for more power or performance necessarily I would rather get better gas mileage.

 

Try it and see if you like it. Any programmer will lead gains better than an intake.

 

Awesome thanks!
