Banks Power Six-Gun Diesel Tuner 61022

The Six Gun is designed to increase injection timing and rail pressure to obtain the +126 HP/+290 lb-ft TQ. (All done within spec to be sure you don’t cause any issues with the engine.) The increase in HP will better your fuel economy depending on how the truck is being driven and supporting modifications.

As per Banks: “Some people think that once airflow is increased, additional fuel must be added at all times, and that would hurt fuel mileage. This is not the case during normal driving. Increasing airflow means an engine doesn't have to work as hard to overcome pumping losses. In other words, power that was previously consumed by pumping losses will be available to do work after airflow enhancements have been made. Or, looking at this from the economy standpoint, the same amount of work can now be done while consuming less power (fuel). So in effect, what really happens is that during normal driving, fuel consumption required to achieve equal acceleration or cruising speeds will be less than before the flow enhancements were made.

Because it is improved airflow that increases engine efficiency, it should be noted that power "chips" that simply increase fuel delivery do nothing to improve fuel economy. The same can be said for bigger fuel injectors. Both power chips and bigger injectors simply add fuel to make power. They do nothing to reduce pumping losses or improve the efficiency of an engine. This is just one more area where the Banks approach of "first air, then fuel" adds overall operating value to a vehicle.”

All programmers generally work on both Auto and Manual Transmissions unless noted otherwise on the website.

Level 1 is stock. Each additional higher level adds approximately 20% of the available power increase. (Example: Stock, 20HP, 40HP, 65HP, 85HP & 105HP)
