why you need a tuner

If you’ve installed tires that are larger or smaller than original equipment tires, or if you have installed a ring and pinion gear set with a different rear gear ratio, the Speedometer Calibrator allows you to re-program for correct speedometer and odometer readings, as well as correct part-throttle shifting. The vehicle’s computer calculates your vehicle’s speed based on the diameter of the stock tires. If you’ve installed taller or shorter tires, or changed the differential gear ratio, the vehicle’s computer doesn’t know how fast your vehicle is going. As a result, the automatic transmission may not shift correctly and the speedometer readings will not be accurate (as required by law).

why regear?

Adding a taller tire puts more space between the ground and the axle center point, which lengthens the leverage arm. This decreases the amount of force applied at the end of the arm (torque to the ground at the contact patch of the tire). Making matters worse, it takes more torque (which uses more fuel) to move a heavier wheel-and-tire combo, and bigger tires are almost always heavier. Therefore, adding larger tires to your truck almost never helps economic or acceleration performance. The small exception this rule may be the diesel truck. Some diesels trucks have so much torque that the effects of adding a mildly taller and heavier tire are negligible and they can actually get better fuel economy and see almost no power loss.

why chip tune/remap your ecu?

More horsepower and torque delivered to the wheels. Great for getting better power delivery on a trail or wanting to show off at a stop light. Extra performance is not the only thing you can get from a remap. The economy of the car can often be increased as well, but this depends on how the car is driven. In an ideal world, you won't drive any faster than before and you'll see better fuel economy. Of course what tends to happen is that you have more performance from the remap, so you use the extra performance and end up using more fuel than before. Once you get used to the power and start driving normally again, you'll see better economy. It is also possible to get a remap that is specifically designed to increase economy. Performance is compromised at the cost of economy with these sort of maps, but this is something some people are happy about since they don't care about performance and just want more MPG.

why an aftermarket exhaust?

More power

One of the most interesting things about adding an aftermarket exhaust to your car is the fact that it can offer more power and performance. While it won’t deliver the same kind of performance boost a turbocharger or supercharger will, you can add several horsepower to the system by reducing (but not eliminating) back pressure. While back pressure is necessary, it can stifle your engine somewhat if it’s too high.

Improved fuel economy

You might not think it, but adding an aftermarket exhaust system to your car can have an impact on the amount of fuel your engine consumes during operation. Again, the numbers won’t be astronomical, but you can definitely see a boost in fuel economy, particularly if you opt for a full exhaust replacement rather than just a cat-back or axle-back replacement.

Sound

This one may or may not be important to you, depending on your age and preferences. An aftermarket exhaust can greatly improve the sound of your engine.

Choosing your system

There are three main types of aftermarket exhaust systems on the market:

  • Axle-Back: This type of system replaces the system from the rear axle to the muffler and has the least effect on performance and fuel economy.

  • Cat-Back: A cat-back system replaces the stock exhaust system from the catalytic converter back to the muffler, and has a moderate effect on fuel economy and engine performance.

  • Header-Back: A header-back exhaust replacement completely removes your stock components and replaces them with aftermarket options. This has the greatest impact on performance and fuel economy.

why a cold air intake?

1. Increased Acceleration

With the right air intake, vehicles can experience increased horsepower. While this varies from vehicle to vehicle because of the interplay of all the components, new air intakes can tack on about five to 20 horsepower to the current speed. Air intakes can also increase the engine's responsiveness when speedy acceleration is required. Because there is more air available and ready for combustion with aftermarket air intakes, the engine reaches your desired speed faster compared to the stock intake that come with a car. Those who enjoy racing cars or who like a quick acceleration as soon as the traffic light turns green should consider getting aftermarket air intakes.

2. Greater Fuel Economy

Engines rely on a mixture of fuel and air to create an explosion that powers the car. When there is not enough air pumping through the engine, the vehicle consumes more gas to compensate for the lack of oxygen. Because stock intakes that come with your vehicle are designed to be quiet instead of fuel efficient, they tend to use more gasoline as a result. Pumping in more air can reduce gas consumption and translate to savings on fuel expenses for the car owner. For those who are concerned about fuel efficiency, new air intakes are a great addition to one's vehicle.

3. More Effective Filters

Stock air intakes that come with most standard vehicle models normally have disposable paper filters to catch debris. While these filters do their job in trapping particles that may potentially wreak havoc to the engine, the filters eventually require replacement. Aftermarket air intakes, on the other hand, are equipped with filters that typically have to be cleaned every 25,000 to 50,000 miles. This not only saves money but it also provides a more effective filtration method that not only keeps debris out but also lets more air inside.

4. Enhanced Sound

Those who like the aggressive sound of a roaring car engine should enjoy most aftermarket intakes. Because more air courses through the engine, it produces a sound that many car lovers find thrilling. For those who prefer the increase in engine efficiency without the sound, there are also intakes that can muffle noise out while still providing the same level of performance.

5. Better Overall Performance

With the simple installation of an upgraded air intake, car owners can increase the performance of their vehicle. Whether you decide to go for the short ram or the cold air intake, most of the time, these aftermarket air intakes can increase the vehicle's efficiency, speed, power, and sound. When choosing between a short ram or cold air intake, it is important to take a look at the vehicle's engine configuration. Purchasing a cold air intake is ideal because cold air requires less fuel to spark than warm air from a short ram intake. Still, at the end of the day, short ram intakes are better than OEM air intakes. Last but not the least, make sure that the intake pipe placement is above flood water levels if your area is prone to this problem.
