What is the optimum speed 4 miles per gallon?

The Energy Saving Trust says that the most efficient speed you can travel in a car in terms of achieving the best fuel economy is 55-65mph. Any faster, though, and the fuel efficiency decreases rapidly. For example, driving at 85mph uses 40% more fuel than at 70mph (oh, and it’s illegal too).

Does tuning ruin gas mileage?

So no, tuning usually gives you more power, but even if in theory it could give you a fuel efficiency gain, in fact it will increase emissions a lot more to get that.

Does ECU tune lower mpg?

The ECU runs the car engine slightly rich so that Cat has enough fuel to stay hot enough to work. You can increase the air to fuel ratio to gain about 10% increase in MPG. When tuning, just keep leaning out the engine until you get a couple of 10ths slower 0–60 time.

Will a remap improve MPG?

For example, it’s a common belief that remapping a vehicle has no effect on fuel economy, however, this technically isn’t true. As the result of ECU remapping, a car usually sees an increase in power, which can come at the expense of higher fuel consumption.
