Can you comment on my MPG ratings?

Since the plenum upgrade, the Porsche on board computer indicates substantial increase in HWY driving 37 MPG (results of 3 months of monitoring).

Please comment.... thanks!
Onboard computer is often misleading and inaccurate regarding mpg. To check your results, log your mileage, log gals used, divide miles/gal.
