Not every ECU tune is about a horsepower increase. Sometimes customers want to improve fuel economy. This actually happens with every tune if you dont use your lead foot 🙂 This customers 2002 Audi A6 3.0L wagon drove to Vivid Racing from California to have his ECU flashed for better MPG. To flash the ECU, we removed it from the car which took only 5 minutes as it was easily accessible. The customer drove from Long Beach to Gilbert averaging about 360 miles to the tank. His return trip home he was hoping for around 420 miles to the tank driving around 65mph. Custom ECU tuning for improved fuel economy is available at VR Tuned.
