MPG of modified cars.

whats not to get. the car is tuned properly. a stock gsr got 31mpg, now it is in a lighter chassis, the car can be run leaner than the stock ecu allowed, the motor is more efficient. with sane driving habits why is it so unbelieveable that my car has the ability to get 5mpg more than stock.

exactly what i was wondering

i think they mean

400,000mpg if theyre pussy footing it, and 4mpg if they’re driving like they have a sack.

Used to get 26mpg in my Saab… down to 16mpg in my GTO

12-14mpg in my canyon, 20-22 mpg in the tsx

i get 22-23 average in my car.
