Guys I am doing my figures from pumping gas (I filled up 19 gal yesterday and drove 300+miles so far and I still havent reached 1/2 tank) and I am using info from the trip computer. both are correlating really closely maybe off by 1-2 mpg... still it does not negate the fact that at an increased hp level the car is under less strain to hold a given rpm...
for example:
maintaining 75mph in 6th gear stock required about 30+% throttle position...
maintaining 75mph in 6th gear TT'd required about 22% throttle position...
I am seeing an increase in motor efficiency and can sustain higher rpm's with less throttle input. Therefore, the motor is able to get higher fuel economy.

btw rcz... I have been driving a TT G37 for 2 months now
