Default poor MPG

I just replaced the injectors on my 04 duramax and the mpg is worse than before. Any suggestions.

You posted this in the wrong section, this is 06-07 maybe a Mod could move this to the 04 LB7 section

But if you could tell us about your truck, what mods you have done, etc.

does it smoke? have you checked the oil for fuel?
