If you’re looking for an easy, plug-and-play mod to give your diesel truck more power and torque, a tuner is the way to go. These little modules plug into your OBD2 port or connect to your wiring harness and access the computer systems that control your engine and other components. They make it easy to run programs that fine-tune your truck for specific applications like towing, mpg efficiency, or race tuning. URL willysworkshop.com.au
Most tuners are simply a program that tells your truck to dump more fuel and air into the cylinders for a powerful combustion cycle, or to ignite the mixture slightly sooner (called advancing timing). This allows your diesel engine to run more efficiently by getting more horsepower and torque out of each drop of diesel and ounce of air.
Plug and Play Diesel Tuners: Easy Power Boost for Your Vehicle
Some tuners also include an economy mode that focuses on saving your fuel costs by using less diesel and air while still improving power. Many manufacturers have even developed a monitor that allows you to see what your truck is doing in real-time through a window on the dash.
Generally, plug-n-play tuners are easy to install and won’t void any warranties on your diesel truck. But they’re not the holy grail of performance modifications, and you’ll need to add other upgrades like cold air intakes, exhaust systems, and more to get the best results. Also, most aftermarket parts require that you set the tune before you install them.
