12v Cummins engine

Cheap 12v Cummins Mods

Looking to mod your 12v Cummins on a budget? Both 1st and 2nd generation 12v engines feature a mechanical injection pump with adjustments to alter various fueling characteristics that potentially may unlock measurable power for cheap.

Diesel particulate filter

DPF Delete dilemma

To delete, or not to delete, that is the question. We dive into the controversial topic of deleting and disabling a diesel particulate filter system. While the obvious improvements in reliability, performance, and fuel economy are attractive benefits to a DPF delete, there are many aspects to consider before moving forward.

Cummins heater grid

Cummins Heater Grid Delete

Who needs a heat grid? Well, some of us might, but for those who live in warmer climates it may only serve as an unnecessary restriction and deleting the heater grid on the 5.9L Cummins has been proven to allow for greater airflow potentials, albeit marginal in many instances.

6.9L, 7.3L IDI Injection pump (Stanadyne DB2)

IDI Injection Pump Tuning

Tuning the 6.9L and 7.3L IDI diesel is a fairly simple task requiring only basic hand tools, a pyrometer, and a few hours of downtime. By adjusting the fuel settings on the Stanadyne DB2 injection pump, IDI owners can find the sweet spot between maximum power and minimal smoke, which coincidentally can send EGTs skyrocketing into the danger zone.

Supercharged diesel

Super-Turbocharged Diesels?

Although not particularly common, supercharger kits are available for many popular diesel applications. By "twincharging" your diesel, you can overcome turbocharging's inherent flaw - lag. Throwing a supercharger into the mix yields far greater throttle response and low rpm performance than turbocharging alone. Learn more about supercharging, how it differs from turbocharging, and how the two forced induction processes can compliment one another.

Water methanol injection cutaway

Water Methanol Injection Explained

It's fairly well known at this point that injecting water into the hot intake air of a turbodiesel yields significant improvements in performance and efficiency. As a byproduct, cooler intake temps also translate into cooler EGTs. Learn more about water methanol injection, how it works, and why anyone can benefit from installing an aftermarket system.

Diesel propane injection display

Diesel Propane (LPG) and CNG Injection

Diesel propane injection was relatively popular when it first came to market. However, it's become a widely controversial modification with skeptics claiming the LPG/CNG injection is not ideal for the diesel cycle and proponents pointing out the potential for massive fuel savings.
