How do I get more power out of my 6.7 Cummins?

Tunes primarily improve power by increasing turbo boost levels. When running higher boost levels bringing more air into the engine is necessary to reduce stress on the turbo and improve its ability to spool quickly. Therefore, we recommend going with a performance intake system to increase airflow into the engine.

What mm turbo is on a 6.7 Cummins?

2013 - 2018 6.7 Cummins Turbo

It has an upgraded 63.5mm billet compressor designed to provide greater airflow and to lower exhaust gas temperatures.

Are 6.7 Cummins reliable?

That said, the 6.7 Cummins is a fairly reliable engine overall. This is especially true if you opt to delete some of the emissions equipment like the DPF and EGR systems. Beware of potential emissions or legal implications, though.

The factory fuel system on your 6.7L Dodge Cummins consists of your underbed fuel tank, fuel or lift pump, high pressure CP4. 2 injection pump featuring a twin piston pump that can handle up to 39,000psi, and electronically controlled injectors (simplistically put).

What does a boost fooler do?

The Boost Fooler will allow you to increase turbo boost to compensate for the added fueling modifications you have made. Enabling your turbo to produce more boost will increase overall horsepower and torque and lower your exhaust temperatures.

Does the 6.7 Cummins have a wastegate?

The 6.7 Cummins turbo system does not have a wastegate and it has a 60mm compressor wheel. The exhaust flow varies over the turbine wheel, which allows the system to respond more quickly at lower speeds.

How much HP can 68RFE handle?

This kit re-works the valvebody and TCM to where the 68RFE can live at 500 to 550 hp, but any more than that and the truck owner will have to start delving deep into the transmission.

Is 30 psi a lot of boost?

regularly run 30psi of boost on pump gas (even 91oct) and even more with race gas or meth injection. Now i know a lot of people will say that you have to remove timing to run more boost and you don't make any more power but the fact is it works great on other cars.

How can too much boost damage an engine?

Increasing boost (within reason) will force more air into the engine, so more fuel can be added to increase the power. So in general, if you add more boost and have an engine tuned to suit will give you more power. Too much boost can cause turbo or engine failure.

What is considered high PSI for a turbo?

With newer diesels, boost pressures can be as high as 40 psi, yet the engine will remain reliable, and make three to four times the power of a naturally aspirated diesel. A turbocharger in its most basic form consists of only a few parts: a frame, shaft, compressor, turbine, and compressor and exhaust housings.

Is 10 pounds of boost alot?

The reason so many folks cite 7-8 Lbs as a maximum safe boost level is because of the amount of effort, expertise, and $$ it takes to go beyond that. Most of the bolt-on FI kits that ship with a "canned" tune and questionable fueling are going to play it safe and keep things at a lower overall boost level.

At what RPM is turbo activated?

A decent turbo hits full boost at 3k rpm, but it varies depending on the mechanical efficiency of the turbo and how much exhaust is being put out.
