Just bought a 2012, have 1,000 miles on her what are the options to get better fuel milage? Its a Mega Cab and I love everthing about it just want to get better milage. I want to keep it stock it has to last me a long time.

 

This question will fit better in the "High performance and accessories" forum since you used the word "delete". Delete and "keep it stock" aren't synonymous. If you want to keep it stock so that your powertrain warranty will remain valid, then you have very little options to improve fuel economy. Other than keeping the tires aired up (and close to the stock size) and driving conservatively there's not really much more you can do. If you do a lot of highway driving (as opposed to city) you can unplug the connector on the EGR valve and gain about 2 mpg. It will throw a code but shouldn't mess with your warranty. Just don't idle a lot (city driving) or your DPF will fill up.

Deleting will boost economy by about 3-4 mpgs highway, but more importantly your engine should last much longer because of the clean, fresh air it will ingest and oil change intervals should double. Ironically, this would put your powertrain warranty in grave jeopardy, even though you're improving the longevity of your engine. Anyway, read the sticky at the top of the "High performance" section for everything you want to know about deleting.

Congrats on the truck! Be sure and post pictures of it.
