When it comes to improving the performance of your Duramax, Cummins, or Powerstroke, diesel tuning is always a great place to start. It offers some of the best value when it comes to price and performance and can make your truck feel like a whole new vehicle. However, when it comes to choosing which type of tuning to go with there seem to be two distinct yet similar options out there, Box Tuners and Custom Tuning. This article will help you decide which option is best for you.
How They Work
Box tuners manipulate the data stream of different engine sensors to provoke a desired engine response. In most cases, this consists of manipulating map sensor values in order to trick the ECM into adding more fuel into the combustion chamber. The idea behind this is that most diesel and even gas engines run on the leaner side of air and fuel mixtures. By increasing the amount of fuel in the combustion chamber more air is able to be burned, which in turn creates more power.
