You need a monitor, not a tuner, I suspect you have stored codes for other problems with only 13Mpg. Have you checked your oil lately?

Sent from my phone that somebody didn't help me get.

cleaning it is hit or miss. If the electronics are failing cleaning won't help.

Oil can be a huge difference in a 6.0. My truck with Dino oil in it got about 12. When I switched to rotella synthetic it was up to about 15-16.
