I wouldnt mind having an extra 50HP in my 2011, and I have heard people mention "mileage tunes" meaning- tunes that add a little power, but more MPG.

who is running one of these ?

Pros and cons ?

with a mild tune, would I need to add a Pyro meter etc ?

any issues with the DPF muffler system? not looking to delete that and get fined by the DOT as I use this truck for work....

thanks
