Superchips’ sophisticated performance electronics are designed to enhance your performance – from fuel economy to towing to racing; we have the products to meet your needs. In an era of high fuel prices, most customers are interested in improving their fuel economy. Our products can help. Here is a brief overview of how our products improve fuel economy, our test procedures for validating our claims, and tips on improving your mileage.


With the Flashpaq or TrailDash we have a specific Mileage tune that offers an increase in timing of the fuel delivery to optimize cruising fuel economy. With advanced timing of fuel delivery, you get a more complete burn within the combustion chamber. A more complete burn is equivalent to getting more power out of the same quantity of fuel. This is the first way our products serve to increase fuel economy – by getting more power out of the fuel you already use .

When towing or driving up a steep grade, the increased horsepower offered by the Flashpaq or TrailDash allows your truck to run in a higher gear, reducing fuel sucking high RPM operation. This is why we consider our products to offer the best of both worlds – increased horsepower and improved fuel economy. And, as an added benefit, less downshifting not only means improved fuel economy; it can help to prolong the life of your transmission.

Atomization is the process by which a bulk liquid is turned into a spray. Our products improve the atomization of your fuel. We achieve this by increasing fuel pressure, which creates a finer mist. The increased fuel pressure achieved by our performance electronics improves your fuel’s burn efficiency, thereby improving fuel economy by (once again) getting more out of the fuel you use.

DYNO TEST – The Mileage tune was developed and tested by Superchips’ engineers using a SuperFlow dynamometer to duplicate typical driving conditions. Both input and return fuel lines from the test truck were run into a separate tank containing a known quantity of fuel placed on an extremely accurate digital scale. With the truck fully warmed, the truck’s cruise control was set to 70 MPH in overdrive and a constant load applied to simulate highway loads. The weight of the consumed fuel was then subtracted from the original weight and converted into MPG.
Repeated test results showed the Mileage tune consistently delivered up to a 7% improvement in fuel economy (depending on year and model of the vehicle) and increased horsepower. In order to ensure accuracy, several tests were performed and an average made with and without the tuning product using the same conditions on the same dyno.

ROAD TEST – In order to validate our dyno test, Superchips’ engineers also conducted a repeatable road test. The idea of the road test was to calculate MPG of the vehicle stock vs. at a programmed level. Using a test loop of 42 miles, Superchips’ engineers took numerous test runs stock and in a programmed level in order to determine the fuel economy benefit of our products under “real world” conditions. Running the route numerous times, the engineers returned each time to exactly the same fueling station where they started, allowing them to refuel the vehicle, record the traveled mileage, calculate fuel consumption, and reset the trip odometer for the next run.

Our engineers picked a filling station and a pump they could return to each time and drew a bracket on the ground and on the driver’s side tire to ensure they parked in the same location for the start and finish of each run. They would then fill the tank to a reference point on the filler neck of the truck’s fuel tank that was slightly below the filler neck vent to ensure a repeatable amount of fuel was used. They would then reset the trip odometer and enter the on ramp of the freeway. Paying attention to exact speeds used and throttle habits, the engineers would then accelerate moderately until reaching 55 MPH. They would then set the cruise at 55 MPH and hold that speed until reaching a designated mile marker along the route. At that mile marker, they would then accelerate until reaching 65 MPH until reaching the exit for the turnaround point of the route.

Once the driver exited, he would immediately enter the on ramp of the same freeway to return to the starting point. Accelerating moderately to 65 MPH along the same stretch, they would hold this speed until they reached the same designated mile marker from the opposite side, where they would decelerate to 55 MPH until they reached the freeway exit at the start of the route. They would then drive to the same pump and park in the same bracket to ensure accuracy. They would then record the mileage, fill the tank to the exact reference point in the filler neck, and record the number of gallons used. They would then repeat the cycle three times each in stock mode and in a programmed state. To ensure accuracy, they would take the average of the three runs per cycle (programmed and unprogrammed).

Repeated test results demonstrated an average increase in fuel economy of 7% while using Superchips’ tuning products.
