The Predator performance module is a really good choice , will make around 115 hp. On a stage III , and if you read the latest article ,in TDR its coming to light that fuel and boost boxes actually increase timing and duration, this is achieved by the computer seeing the offset fuel and boost sensors reading and adding duration and timing to make up for the perceived deficiencies .
Fuel economy is an added benefit of increasing the power output of diesel engines, more power , means that BSFC or Brake Specify Fuel Consumption , or pounds of fuel burned per horsepower hour is decreased . This means in layman’s terms that each hp cost less fuel to make. If a truck cruising at steady state uses a given amount of hp to stay at that speed ,and you pay less pounds of fuel for each hp produced , you achieve a increase in fuel economy.
I always try and stay out of the my box is better then their box argument . but with the latest articles in TDR on fuel boxes I thought I would expound on my ideals on diesel aftermarket performance .
Give Predator a call, the modules work great and the power gains are documented.
