Default Gas milage after mods....
Sucks.

I was averaging about 20-21 MPG prior, now seeing 16-17 MPG... Haven't even started beating on it yet.

Car is a daily driver, I put about 60 miles on a workday with varied driving conditions so I get pretty good averages..

I know that a good tuning will help, saving my money for the full treatment with TJWong... (O2 sensors are less then 6 months old)

With the mods listed in my sig, should I expect this?

On mine just stock intake and heads but do have hedman headers and true dual exhaust. I too noticed my mileage dropped 3-4 miles a gallon from 22 to 18. I did cutback my plugs but still had the same mileage as before I did the cutback. Wandering what is going to happen when I port the intake and get bigger runners? I feel your pain

Do you guys have automatic transmissions? I thought guys with 350 rwhp running 4.11's were getting over 25mpg but that is with the manual.
