A. Absolutely not! They may look alike, but that’s where any similarity ends. Diesel Tunes™ is designed by today’s leading diesel performance engineers. Its sophisticated electronic circuitry and advanced capabilities far surpass any other diesel performance chip on the market—for power, for fuel efficiency, for safety, for warranty protection. The more you read, the more convinced you’ll be of its superior capabilities and extraordinary value.

A: There are many factors that affect mileage, including condition of the engine, terrain and driving habits. Our modules are designed to easily provide 20% improvement in miles per gallon. Some drivers will experience more modest gains if they drive with fast stops and starts and heavy acceleration (foot on the floor). The Workforce Module will provide mpg increases whether you are driving highways or towing your heaviest loads. Follow the suggested maintenance included in the instructions for best results.

A: Today most standard diesel chips cost $495-$895. But because you are “strongly” advised by the chip makers to add a Pyrometer and Boost Gauge you will need to add another $250-400 in additional parts and equipment to the purchase price of their Chip. Also since you will be using the “higher horsepower” settings on the Chip, you need to get more air in and out of the engine to keep high exhaust gas temperatures from damaging your engine. Because of this you will need to spend another $250-$400 on a larger Air-Intake System and $500-$800 on an exhaust system.

So in order to safely operate their Chip that costs you $495-$895… you need to spend an additional $1000-$1500… (And heat damage can still occur!)

Remember the Diesel Tunes diesel chip does not raise EGT's so you eliminate the need to spend the additional $1500 making it the most cost effective diesel performance product on the market.

A: Diesel Tunes is a revolutionary “simple to install Black-Box” that uses cutting-edge digital microprocessor technology to improve the performance of Dodge Cummins, Ford Power Stroke and GMC Duramax diesels. Our chip provides up to 33% more horsepower and torque as well as fuel mileage improvements ranging from 10-20%.

Unlike other products that simply pour more fuel in, Diesel Tunes chip improves the combustion efficiency of the diesel fuel you’re already using through precise fuel system management. This is accomplished without changing factory computer settings or increasing Exhaust Gas Temperatures (EGT’s), making it the most warranty-friendly option available.

A: RESULTS! The Diesel Tunes diesel chip produces substantial power and fuel economy increases WITHOUT ADDING MORE FUEL to the engine.

There are two main differences between the Diesel Tunes module and standard diesel Chips and programmers. The Diesel Tunes does not over-fuel your engine and is guaranteed to substantially improve fuel mileage at the same time.

Side by side diesel chips may look the same but it all boils down to HOW they produce that power and what is the long term effects on the engine. The true bottom line is not how much power diesel Chips can produce, but how safe is the method used that produces the power. The wrong diesel chip can potentially harm your engine due to increased engine temperatures under load.

Standard diesel chips use a method of adding more fuel or “over-fueling” the engine to produce power. They do this by changing the Pulse-Width of the injector which means they change the factory computer setting so that the injector sprays fuel longer thus adding more fuel to the combustion cycle.

While these other performance products do increase power… this “over-fueling” METHOD is also the primary hazard associated with engine damage and failure. If you take the risk and use this method of “over-fueling” your engine it is highly recommended by the chip manufacturer to modify the stock exhaust, intake system and add gauges to monitor and control the added heat caused by over-fueling. This is good advice because if you don’t get rid of the excessive heat produced, you run the risk of damaging your turbo, pistons, and exhaust manifold!

Diesel Tunes separates itself from other diesel chips by improving the atomization of the fuel as it sprayed into the combustion chamber. The smaller fuel particle is able to bond to more air producing a more complete burn. By burning every drop of fuel inside the combustion chamber you get increased performance while your Exhaust Gas Temperatures (EGT’s) remain normal.

A: Diesel Tunes precisely regulates fuel injection pressure within factory specifications in order to enhance the atomization and dispersion of injected fuel. Controlling the pressure of the fuel plume sprayed into the cylinder the air-fuel mixture optimizes making for better more complete combustion of existing fuel. We manipulate these fuel pressures and still stay within factory recommended pressure ranges. The result is that greater volumes of energy are released at combustion without adding more fuel to the engine. You get better fuel economy, safer power gains, cleaner emissions and longer engine life… with nearly ZERO rise in exhaust gas temperatures. Standard diesel chips simply cannot accomplish these results.

A: With built in safety features you enjoy peace of mind under hard pulling conditions because your EGTs remain normal. No longer do you need to purchase expensive gauges and bigger exhaust systems saving you hundreds of dollars over traditional diesel chips. With the excellent increase in torque and low-speed pulling power you can expect to gain a gear or two and increased speed of 20-30 mph on steep grades. That additional bottom-end torque gives you the sheer power you need to always be the first one up the hill.

With demanding loads Diesel Tunes removes the sluggish feel in the bottom end and produces a smooth power band all the way to the top. This improved throttle response will help you pass slower traffic without leaving you hanging out in the danger zone or having to wait for a mile of clear straight stretch. Moreover, even though Diesel Tunes is designed for more power, in most cases you will also increase fuel economy ranging from 10 to 20% because of the increase in low-rpm torque and improved combustion efficiency of your engine.

A: Actually the Diesel Tunes Module is not doing anything truck manufacturers can't do themselves by fine tuning their engines. Our product manipulates factory settings to produce a more optimal performance output and power curve by "fine tuning" stock settings with a precision tolerance. This is what makes us unique.

Over the past several years manufacturers have been substantially raising the horsepower and torque levels of their engines without changing the engine’s cubic displacement. They do this because they intentionally under-tune their engines to start with.

As engine manufacturers increase horsepower, they also continue to move the optimal power curve further outside the driving range. In fact, you would have to drive your truck as high as 3100 rpm's to actually get the advertised horsepower you paid for.

Not only that, with the optimal performance curve out of reach at normal driving speeds, your engine is also robbed of precious fuel mileage costing you hundreds of unnecessary dollars at the pump.

The good news is, as the Diesel Tunes Module manages your engine’s fuel delivery, the high-end HP the torque curve is relocated to a usable 1700-2300 RPM range. This enables you to not only tap into the power when and where you need it most, but also gives you impressive mileage improvements ranging from 10-20%.

Best of all, because the Diesel Tunes diesel chip simply relocates the high-end performance to a usable low-end range, it never exceeds the manufacturer’s power train limitations or fuel rail pressure levels.

A: YES. Don’t let its advanced technology and simple design fool you. Even if you have never lifted the hood of your truck, you will have your Diesel Tunes Diesel Chip installed by following simple instructions. The module snaps into your engine wiring harness with factory style connectors. Installation time and ease of installation varies with truck models.

A: The module is undetectable by service diagnostics and can be easily removed before servicing.

Most vehicle owners are not aware that they are protected by the Magnuson Moss Warranty Federal Trade Commission Improvement Act of 1975 (15 U.S.C. 2302(C)) for the installation of aftermarket products. Under this federal law, after market equipment that improves performance does not void a vehicle manufacturer's original warranty, unless the warranty clearly and conspicuously states so. It is advised that you read your vehicle warranty & manual thoroughly.

A: The Diesel Tunes is designed with safety as a number one factor. It will work well within your drive-train factory limitations and in many cases you will notice improved shifting performance because of the added power.

A: You have nothing to lose because you are protected with our 30 day Performance Guarantee and a one year warranty.
