Combustion process using Dr. Performance products on diesel engine means exit gases are a cooler 950 degrees (EGT).

The other guy's combustion process

puts exit gases at 1300 degrees (EGT)

The Dr. Performance System is based on COMBUSTION EFFICIENCY resulting from microscopic fuel plume distribution.

As a result of optimized fuel distribution you can expect the same fuel economy and in some cases you may gain a mile or two per gallon.

You will have a great band of power stretching through every single gear and increased throttle response.

Best of all Dr. Performance! does not void your manufacturer's warranty* and does not break-down engine components. Your diesel will run better than it ever has before!

Prior to the invention of the Dr. Performance! System, the only method readily available to get more power from a diesel engine was to add more fuel. This is known as "over-fueling". This requires you to modify your ECM with after-market electronics or "chips", which circumvent factory fuel delivery, turbo boost, and other specifications will void the factory warranty. Over-fueling will significantly shorten the life of your engine, or worse, cause it to fail completely. The reason for this is that your engine is not designed to burn this additional fuel. This unburned fuel greatly increases friction and wear on the cylinder walls and rings and can raise exhaust gas temperature to dangerous levels when you use the extra power. Factory warranty will be jeopardized. The Dr. Performance! System is based on COMBUSTION EFFICIENCY resulting from microscopic fuel plume distribution. You can expect incredible rear wheel horsepower and torque gains. The power increase depends on which engine you start with.

The Dr. Performance! System produces REAL WORLD power gains - we call this usable power - all the way across the power band at the speeds and in the gears where you need it. Our system also produces a very flat torque curve. This means, once our maximum torque is reached, torque falls off very slowly as RPM's increase toward maximum horsepower. This gives your engine excellent pulling characteristics by keeping torque output high all the way up the power band until maximum horsepower and RPM is reached. (JUST IMAGINE!) One of the most frequent complaints we hear about stock engines is slow throttle response. Our system significantly increases throttle response right off the bottom and all the way across the entire RPM range. You'll know it when you push on the pedal. Improved throttle response combined with the extra power, results in a much more enjoyable driving experience. You will be able to merge, pass, and move away from undesirable traffic situations in ways you never thought possible with a larger vehicle. You may be able to accelerate in up to half the time. Your speeds under load will increase 20-35 MPH on grades of 5 to 8%. Grades of 5% or less will no longer slow you down at all. In the first few seconds behind the wheel, you will definitely feel the difference!

Increased power doesn't do you much good if you can't use it. Unburned fuel creates heat because it continues to burn in your exhaust manifold and turbo. This raises exhaust gas temperatures (EGT) beyond acceptable levels and can cause a catastrophic failure by literally melting parts of your engine. Those companies that advocate adding fuel to increase power suggest you add a pyrometer to monitor your exhaust gas temperature. This is a good idea, because you'll need one! Every time you use the extra power that over-fueling provides, for an extended period, such as on a grade, your EGT will rise above acceptable limits. At that point you will have to back off the throttle and shift down to avoid damaging your engine. They will also tell you that a maximum EGT of 1350 degrees is acceptable, but IT IS NOT. At 1350 degrees metal glows red hot. Temperatures this hot can permanently damage your engine. Cummins recommends a maximum sustained EGT of no more than 1050 degrees. High exhaust gas temperatures also raise coolant temperatures, causing your engine to over heat even more. With the Dr. Performance! system, there is no need to add a pyrometer to monitor your exhaust gas temperature. Our system WILL NOT raise exhaust gas temperatures above acceptable limits - EVEN WHEN YOU USE THE EXTRA POWER - because we DO NOT add more fuel than your engine is already designed to burn!
