Precision Tuning
At the heart of the Quadzilla Stealth Tuner is many long hours of precision tuning combined with thousands of miles of real world testing. Quadzilla combines 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 the Quadzilla Stealth Tuner has the lowest exhaust temperatures on the market. Perhaps the best part of the Quadzillla 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 if you have the Quadzilla Stealth Tuner installed.
