Rod

you'd think it would eat fuel ! ! !
When cruising, a well mapped engine will consume 15 x more air than fuel
When going hard, this drops to around 11x more air than fuel.
Most of your horsepower comes from the consumption of oxygen, not fuel, in a laymans sort of way......
Rods is obviously well mapped.. ive seen Stage 3 Escort Cossies doing less than 10mpg at 40mph in 5th, with no faults
