I do run 4-6+ psi over stock, with the 195 OEM Ecopia tires. Also I added some underbody aero panels that are available in Europe and/or on the Hybrid Jetta.
You will see a slight increase when the engine "loosens" up.
I also recommend the OBDeleven device if you like tweaking your car. A deal at $60, plus full code reader, etc.
Once I had a consistent MPG by 'hand', I was able to adjust the cars display to closer match reality (it was ~7% too high), just one of the many things you can "hack" with the device.
Thats some excellent MPG. I might have missed it, but what tune are you running? I'd love to get one, but sadly will be holding off until warranty is gone. What kind of oil/oci do you run with the added boost?
Mine is only rated for 22 city, 30 highway. I guess the drag of the awd and weight drops the rating quite a bit. Does amazon sell the OBDeleven?
