Re: Tips to improves gas mileage-performance
increased airflow is good for performance but bad for economy. If you add more air to the system the MAF is going to compensate and add more fuel to keep the air/fuel ratio in spec.
Usually the only mod that ever increases power and efficiency at the same time is something that reduces friction. Motor oil and tires are the two biggest factors.
less engine friction and less rolling resistance. Smaller tires have less rolling resistance than big meats.
