Any ideas for better gas mileage on my 2005 z71 tahoe?

[jakelsu777]

I have a leveling kit and im running 285/70/17 procomp xtreme mud terrain. Since i did this, my gas mileage has dropped by about .3 mpg. I will be keeping this car for a long time, so i think it will be worth the investment to upgrade it so it will get more gas mileage. I was thinking of something like the K and N cold air intake system. Any other ideas?

I have an 04 Z71 and average between 18 and 20 mpgs. Short ram intake, magnaflow muffler, custom high octane tune...

I have a s&b cold air intake used about 3 months and a predator programmer for sale off my 04. sold the tahoe.I got 18 to 20 mpg with that set up.

fvck those programmers, weak sauce for sure.. get a custom tune, any reputable tuner will do free re-tunes if for life.
