At the heart of the Stealth Tuner is many long hours of precision tuning combined with thousands of miles of real world testing. We combine the use of fuel injection pulse width and injection timing to create the ultimate horsepower and torque curves. The precision tuned timing maps are one of the reasons our tuner has the lowest exhaust temperatures on the market. Perhaps the best part of the Stealth Tuner is the mileage gain that you will see. We all know that a more efficient engine will gain fuel economy and we know exactly where the stock parameters are lacking. Depending on your driving style, you can expect to see a 1-4 mpg increase!
