ClubCab mean CrewCab ?!!?

 

I haven't gotten any REAL numbers cuz I'm always punching it , but I'm seeing probably 2mpg in town, I'm guessing my highway has gone up at least 2.5, maybe more.

 

But I'm 2wd....

 

Go with the super unleaded tune, your gain-percentage will be much greater.

87/91 tune specifically, but i'm also curious if anyone who has the higher octane tunes is getting better gas mileage than they did with a lower octane before the tune(also taking into account the price difference of the octanes).

 

4 full doors = crew cab
