Photo 2/5 | Low Stall Converter | Daily driven diesel trucks perform best with low-stall torque converters that match the engine’s torque curve. Torque-converter manufacturers can custom-build products to fit specific applications. Custom-built torque converters come in handy when doing diesel conversions.
Photo 3/5 | 002 Dual Batteries | Dual batteries double the amperage to not only help turn a diesel engine over, but to handle the huge electrical loads other components, such as glow plugs, lift pumps, and fuel heaters, place on the starting system when the key is turned. A single battery will work, but usually not for long.
Photo 4/5 | 003 Programming For MPG | Plug-in programmers can provide a slight uptick in fuel economy, provided the person who does the tuning focuses their attention on that aspect of the ECM calibration. That’s why some diesel programmers have an “economy” mode to improve mpg during light-throttle, steady-state driving conditions while other devices are specifically set up for making power. You can’t have power and fuel economy simultaneously; it takes fuel to make power.
