Frequently asked Questions
Any software tuner can strongly influence the engine and expand its capabilities. The maximum amount of additional horsepower depends on the tuner and the car and its characteristics. In general, Bully Dog 40410 can increase the horsepower of the car by about 40 units. If you check the Bully Dog 40417 reviews, you will see that the tuner can give an increase of 25 horsepower according to the claims of many users. At first glance, this is a rather basic indicator. Still, this tuner can also influence other parameters of the engine, allowing you to accelerate the number of revolutions and reduce fuel consumption even with intensive use of the vehicle.
Please note that the range of influences and improvements in engine performance depends on the model of the car and the tuner. This tuner is one of the most functional controllers that help you get maximum control and protect yourself on the road. If you use the tuner with other devices and systems that increase power, the increase in horsepower will be impressive. The turbines, improved cam mechanisms, modern exhaust systems, and other technologies significantly improve the car’s operation and increase its power. The tuner, in turn, allows you to control and change the operation of each system. The total increase in horsepower may be up to 100 when using several technologies together.
If you use the tuner to increase power or torque, fuel consumption always increases, as more fuel is supplied into the cylinders. This is especially true for operating modes for towing and transporting heavy loads in severe road conditions. In such cases, fuel consumption increases significantly.
It is also possible to find the optimal modes for power and consumption, but this way, it is impossible to reveal the power potential of the engine.
The Bully Dog 40415 and 40417 software tuners perform quite efficiently in fuel-saving modes. Consumption per hundred kilometers can be reduced if you set the appropriate modes. This applies primarily to driving on the highway when fuel consumption can be reduced to 4 liters. In fact, the tuner does work, but the consumption depends on many factors, including driving mode and conditions, proper fuel supply systems, and secondary exhaust recirculation. With all systems working together, savings can be much more significant.
The desire to get the maximum out of the car makes many drivers use software systems to increase power and improve other indicators. You will immediately see that the tuners from Bully Dog cope with these tasks very well. It becomes clear right away when you connect the device to your car. The tuners have a lot of operation modes and can allow you to control many car systems, which other similar products can’t do. A significant and safe increase in power is the company’s main priority, which it successfully implements in sports cars. Professional racers use these tuners on a variety of vehicles. Pickups and trucks also use these tuners and work with them with no issues.
Such controllers have a lot of useful features, convenient controls, and high-quality screens. A small color screen fits all the useful and necessary information that you might only need when driving in advanced modes. Tuners also allow you to diagnose and fix incorrect codes affecting the system.
If we make a list of the car features the Bully Dog tuner can influence, it becomes clear that this is a universal and multifunctional device with almost no analogs on the market. Transmission, fuel injection, torque, throttle responsiveness, lighting, and calibration are far from a complete list of parameters controlled through the tuner. The Bully Dog tuners are easy to install, use, and manage, so it makes sense to choose them if you want to control your car’s operation professionally.
General Motors has developed a fuel-saving system on its V8 and V6 engines. The computer can automatically close half of the cylinders to save fuel. Of course, this is an excellent saving system when you do not need additional power and you move in calm conditions. The AFM system is quite useful, but it works automatically and cannot be disabled manually without third-party controllers.
That’s why third-party manufacturers have developed software methods to affect the AGM and disable this feature. With the Bully Dog tuner, you can easily turn off the AGM control system and get a constant power boost. Disabling this function leads to constant fuel consumption and increased power when driving in any conditions, regardless of engine load. Disabling the fuel management system can be useful when towing another vehicle, transporting heavy or oversized objects, or when driving on mountainous terrain. You can enable the AGM function anytime using the tuner, and the car will operate in saving mode again when you need it.
