The #1 way to increase fuel economy is to slow down! The difference in fuel economy between 60-65 mph and 70-75 mph can be as much as 2-4 miles per gallon. Your diesel engine has a specific rpm that produces the most efficency and this is generally very close to where peak torque is located. The 12 valve Dodges (1989-1998) need to run at 1600-1700 rpm, with the 24 valve engines (1999-2002) needing to run 1800-2000 rpm, and finally the HPCR Dodge engines (2003-2007) need to run 1900-2100 rpm. Fuel economy can also be increased by improving the efficiency of your engine which means, releasing energy that the engine is already producing. Improving the engine's ability to breath contributes to the engine's ability to operate more efficiently. An AFE cold air intake system and a performance exhaust system will provide good benefits to fuel economy. On the newer trucks that have catalytic converters we can install a 4 inch high flow straight through muffler and tail pipe. Stanadyne Performance Formula has also been a proven to increase power and fuel mileage by improving the properties of the fuel for a more efficient combustion. The improvement in fuel mileage exceeds the cost of the additive plus you get the added bonus of lubricity improvers, corrosion inhibiters, cleaning agents, fuel stabilizer, and anti-gel. All of these add up to reduced maintenance costs of the engine and fuel injection system.

Performance computer modules are designed for performance improvements and not fuel economy, however they do generally improve fuel economy.  Increasing the power by increasing the fuel to the engine means a bigger fire in the combustion chamber which creates more exhaust flow.  More exhaust flow means that the turbo spins faster and creates more turbo boost pressure.  More boost pressure means that the engine efficiency is improved and if you are not to hard on the accelerator pedal you may achieve better fuel economy.  The computer module, the air intake system and the performance exhaust system all compliment each other to a more efficient engine.
