Not possible.

The highest I have ever seen with a common rail with one of my customers is 25 mpg. 04.5 2WD QCSB, Edge Juice, MBRP 4" turbo Back, AFE stg 2, Flux 1 injectors, HTB264 turbo. Thats in central Texas as well.
I've read about some older 24V (98-02s) doing 26-27mpg

 

I got 22 last weekend on a 300 mile trip to champaigne Ill.

 

Best tank i ever had was 24 Nonstop cruise at 70mph for entire tank. usually avg 20-21.
