CAI and Tuners - Increase highway MPG?

[Andymax]

I don't care what any manufacturer claims...I'm hoping for real world information from folks that have installed and have calculated before and after mpg's. I'm less focused on the actual HP and/or Torque gains...just any real mileage improvements. While were at it...any real world MPG improvements with Tuners that aren't crazy expensive?

I have not tuned but exhaust and CAI I do think helps my truck maintain its 21mpg on the highway with a 2 inch lift and on 35s with a 5.7etq..it does hurt my city driving tho since I like vroom vroom noises

I'd have to agree...21mpg with a lift and 35's is impressive! I really don't want the noise though...I'm on the highway 95% and one of the things I love about the Ram is how quiet it is.

its not that loud when not on it
