This is a remote tune. A specific open sort flash tool is required in order to flash CAT Construction Equipment. If you require the tooling to complete the flash, please be sure that you select the proper drop down.

Note: The exhaust system on the majority of these engines have to be straight piped. They cannot be separated to hollow out the diesel particulate filter. We recommend having piping fabricated together and bypassing the entire system.

In need of more power?
This is a question that we get asked quite often. When it comes to horsepower increases, the best way to explain it is that we are making the engine more efficient. It produces more power, sooner. If you drive the equipment nicely, you will get up to speed faster, keeping the engine load lower - reducing overall load. If there is a situation where more power is needed, you’ll have the extra horsepower that you need! It really is the best of both worlds. 

What is an EGR System, and why remove them?
Exhaust Gas Recirculation (EGR) is a method that is used to control Nitrogen Oxides (NOx) emissions. The purpose of this system is to return a small portion of exhaust gases back into the combustion chamber through the intake manifold. Lowering combustion temperature, resulting in a reduction of NOx emissions. The issue with EGR systems is that the valve can stick open due to carbon deposits. A worst case scenario is that the EGR becomes completely blocked, this will result in poor fuel mileage and a loss of power. When this occurs, it results in engine warning lights and the equipment going into limp mode. The vast majority of exhaust gas recirculation valves power off in the closed position. This means that once they are de-energized, they are in the shut position. On a few select applications, we offer block off plates. These plates are used as a fail safe, to ensure that there is no exhaust coming back into the intake system. 

What is a DPF System, what do you need to do with it?
The diesel particulate filter, or DPF is part of the exhaust aftertreatment system. It’s main purpose is to trap particulate matter, such as soot. This soot has to be periodically burned off, which regenerates the filter. When the soot level reaches a high enough percentage, the engine starts to inject fuel directly into the exhaust system. This creates heat and converts soot into carbon dioxide. Having to deal with regen can cause down time for the machine. In some cases, the DPF will have to be replaced, or cleaned manually. Not to mention it is also extremely restrictive on the engine's ability to push air out. When it comes to removing the DPF canister, the only decision you have to make is whether you hollow it out or straight pipe it!

What is DEF?
DEF, or diesel exhaust fluid is a liquid that is injected into the exhaust system. This part of the exhaust system is called the SCR, or the selective catalytic reduction. It is designed to remove nitrogen oxide emissions from the diesel engine. The issue with diesel exhaust fluid is that because it is 67% water, it can freeze during the winter. This can crack the DEF tank and lead to other problems. Some manufacturers use diesel exhaust fluid as their main, or only, source of emissions control. This can result in high costs, ensuring that the DEF is always full. The catalyst that is used for the DEF is not as restrictive compared to the diesel particulate filter. This means that it can stay in place, even after a reflash has taken place. We recommend that you rinse out the DEF system with water after the fluid has been drained. Diesel exhaust fluid if left alone for a long period of time can crystalize. That is why it is best to make sure everything is clean! 

Emissions tuning is for off-road use only. Please consult your Provincial or State legislation, as this product may not be street legal. Removal of emissions systems cannot be performed on vehicles that are registered for highway use. It is up to the Consumer to know and understand their local legislation prior to purchasing.
