How to Increase Horsepower & Torque in Vehiclesby Contributing Writer; Updated June 12, 2017
Vehicles is a large automotive manufacturer based in Japan. As with most Vehicles their Vehicles enjoy a relatively large supply of aftermarket vendors including a wide variety of performance aftermarket components. Some of these components are designed to replace existing factory components while others are designed as additions to be bolted on the engine. All increase horsepower and torque when installed correctly.

Replace the Ford F-150 factory air intake with a performance aftermarket cold air intake.This will provide improved airflow into the engine as well as a lower overall engine temperature, which will in turn provide a moderate increase in horsepower and torque.
Replace the Ford F-150 exhaust system with a performance aftermarket exhaust system. Doing so will enhance the flow of hot air out of the engine, which reduces engine temperature and improves throttle response. This will increase horsepower and torque, as well as giving your truck a louder, more aggressive sound.
Install a performance computer chip to the onboard computer of the F-150. This option is only available on newer F-150 trucks which have an onboard computer. Performance computer chips reprogram the engine's computer, which manages and controls various performance functions, for maximum power and performance rather than for efficiency.
Install a nitrous oxide injection system. Nitrous oxide injection systems consist of a bottle of nitrous oxide gas and an injection system which is connected to the fuel line. When activated by the driver, the bottle releases a shot of nitrous oxide into the fuel system which provides a huge, but temporary, boost in power. The temporary nature of this power boost makes Nitrous Oxide injection systems ideal for drag racing uses.
Install a supercharger of turbocharger kit. Supercharger and turbocharger kits, also known as forced induction kits, funnel massive amounts of air into the engine, where the air then mixes with fuel. This in turn provides a huge boost in horsepower and torque which can drastically change the handling of the vehicle. Because the change in horsepower and torque produced by forced induction kits can be so dramatic, it is often necessary to upgrade other components of the truck such as the brakes and the tires in order to safely handle this power increase.
Replace the Toyota cold air intake system with a performance aftermarket cold air intake system. Cold air intake systems are one of the most popular performance aftermarket upgrades for most vehicles including Toyota trucks because they are fairly inexpensive, relatively easy to install and have little chance of damaging your vehicle. They provide an impressive boost in horsepower considering their price tag, and the only noticeable side effect is a slight increase in engine noise. Performance aftermarket cold air intakes may even provide a slight increase in fuel economy depending on the vehicle.
Replace the Toyota exhaust system with a performance aftermarket exhaust system. Exhaust systems are also a popular aftermarket upgrade because in addition to boosting horsepower and torque, they also give your vehicle a louder, more aggressive engine note. The boost in power from a performance aftermarket exhaust system is typically comparable to that of a cold air intake system, but they generally cost three to four times as much and require access to the underside of the vehicle for installation. They also increase CO2 emissions and are barred from street use in some states.
Install a supercharger or turbocharger kit onto the engine of your Toyota truck. Supercharger and turbocharger kits provide the greatest gains in horsepower and torque of any single aftermarket modification and are available for most vehicles. They are also extremely expensive and require professional installation. They also drastically increase wear and tear on the vehicle and substantially decrease fuel economy. Further, they may necessitate other upgrades to the truck such as brakes and suspension to accommodate for the extra power. Still, supercharger and turbocharger kits are a popular upgrade despite these risks because they can more than double horsepower and torque.
Replace the stock Magnum cold-air intake with a performance aftermarket cold-air intake. These air intake systems typically provide a power boost of about 8 to 15 horsepower, depending on brand and model. They generally cost between $100 and $200 and are relatively easy to install compared with other performance aftermarket upgrades. Because of their relatively low price and general ease of installation, performance aftermarket cold-air intake systems are a popular upgrade for many types of vehicles. They have few drawbacks other than possibly resulting in a slight increase in engine noise.
Upgrade the stock Magnum exhaust system with a performance aftermarket exhaust system. Performance aftermarket exhaust systems typically provide a power boost of about 10 to 25 horsepower, again depending on brand and model. They generally cost between $300 and $600, but are difficult to install at home because they require access to the underside of the vehicle. Performance aftermarket exhaust systems also increase engine noise, sometimes quite drastically, depending on brand and model. They can also increase CO2 emissions, which may result in the vehicle losing street-legal status depending on your state's regulations.
Install a performance chip for the Magnum 3.9L engine. Performance chips modify the engine's on-board computer for maximum performance, resulting in a boost of roughly 10 to 40 horsepower. Performance chips are relatively easy to install but fairly pricey at about $400 to $1,000. Performance chips can also decrease fuel efficiency and overall engine longevity by modifying engine performance.
Items you will need
Locate the sub-dash diagnostic port on your Cummins-powered motor home. It will be located near the door, below the dashboard, near your left knee when driving.
Install the diesel programmer's included housing onto the dashboard of the motor home by removing the cover from the double sided mounting tape and pressing the housing securely onto the dashboard. Install the housing near to the A-pillar, rather than in front of the steering wheel. The programmer readout should be in a position where you can glance at it quickly, but not take your eyes off the road or block your view of the road.
Run the wire which will install into the sub dash diagnostic port through the opening in the housing and press the programmer into place in its housing, then route the wire down the back or side of the dashboard.
Install the programmer's harness into the sub dash diagnostic port, pressing firmly.
