Engine tuners (Pulsar - only one I've seen that is easy fit) 4. . Anything else I've missStep three is modifications that help with mileage. A cat-back exhaust system and a high-flow intake will add mileage. If you do other mods to add power past these two mods you will start decreasing mileage again because as you add more power than that you will need more fuel. Cliff Notes: 1. Take it easy in the city.Pickup trucks have high coefficients of drag. Fortunately, they're also ideal platforms for adding this highly effective aerodynamic modification. A number of EcoModders have undertaken this task, recording highway fuel economy improvements of between 13-20% compared to an uncovered bed. Sep 6, 2019 · Aerodynamic drag is a minor conce
