How to get my mileage up.?

[smokedout250]

Okay my 07 is getting crap for mileage. After exhuast I'm getting 12mpg. After tuner 13-15mpg.... So how do I get it up? My buddy just bought an 07 outlaw 6.0, he's getting 18mpg

FICM tuning and ecm rollback will help.

+1 on FICM. Keep your foot off the skinny, but im sure you already knew that. I can consistently get 17 MPG in town, and around 20-21 on the freeway. Im running the same tunes as you. Are you running the SRL as your daily driver?

If your truck is loping when its cold, and your fuel PSI wonders with the lope, probably is a stiction issue. I would recommend getting a cycle of Rev-X in, on your next oil change, see if this helps. But would that affect your fuel economy... not sure about that one. Im starting to have a little stiction, and have Rev-X on the workbench ready to go. I havent seen a decline in my fuel economy though.

Might want to try switching out to some synthetic next oil change and add some revx. It fixed my stiction issues. I'd go with Innovative's or PHP's remote tuners.

I couldn't take the wait for one of PHP's loaners, so I bought one. LOL

I would just buy an ficm tuner I guess I'll start looking at them

Also, +1 on synthetic. Im going that route next oil change as well.

 

[smokedout250]

Agreed. You need to go through the runnability with a fine toothed comb before anything else IMO. If you don't have one already, an AE will be a huge help diagnosing anything thats going wrong. There could be a number of components on the verge of going bad that aren't throwing a CEL, but keeping your truck from running optimally.

FICM tuning and ecm rollback will help.

Once you have it running 100%, absolutley do this. The newer flashes kill mileage.

Doing this will help a little too.

Another thing to consider is that in Oregon, you are likely getting winter blend diesel right now. You'll pick up a mpg or two when the switch to summer blend happens.

LMAO. I have a half ton crew cab company truck, so I drive that most of the time, considering I am only home one week out of the month, I only put 6k miles on my truck a year. LOL... save a lot of fuel there too.
