Put the fire back in your Duramax while increase towing power and mileage on your GM Duramax Diesel Pick Up with our new Programmer. Our programmers and update computer codes are designed to be a non-intrusive, easily reversible means of increasing the performance of GM Duramax vehicles utilizing the Allison automatic transmission. This is accomplished by plugging our DurRaptor Programmer into the direct link connector and uploading a new computer code to the PCM (Powertrain Control Module), thereby overriding the factory tuning.

Performance benefits are immediately realized in the form of improved throttle response and increased power. Long-term benefits include improved fuel economy and improved automatic transmission service life. Extensive research and dyno testing as well as customer response have shown there to be no negative benefit from the use of our enhancements to the performance, and the initial costs are far outweighed by the benefits gained by utilization of our module.

How is it Possible?

While our Programer and new codes are designed and calibrated to increase performance, the improved tuning generally results in improved economy, this is due in large part to the inherent calibration design. It all starts at the vehicle factory. Calibration engineers have to weigh several factors into designing a calibration program for any given vehicle, including things like temperature extremes, altitude extremes, driving conditions and fuel quality. To cover a broad range of driving applications and conditions, the programmers will use a "Lowest Common Denominator" method of tuning. This means they will account for the worst driving conditions and fuel quality that is feasible and, while still maintaining reasonable performance and economy, they will base their calibrations on these factors. Unfortunately, this type of tuning is obviously not going to offer the best performance or economy. Our programmers overcome this by retuning the calibrations designed for your given vehicle under your specific conditions. While other manufactures may offer generic performance improvement products, which cover a broad number of vehicles, our engineers design calibrations based on your vehicle specific information.

Using that information, our programmers can design calibration code to provide the best possible combination of performance and economy without adversely affecting the integrity or service life of the vehicle. Such performance tuning also provides for improved vehicle emissions.

What you can expect!

Performance increases for the Duramax-diesel is achieved by dramatically improving the fuel management tables as well as the turbocharge boost controls to increase performance and derivability without sacrificing economy. With automatic transmission functions becoming more dependent on computer controls, there are a large number of performance benefits achieved by tuning the automatic transmission calibrations as well as the engine. As manual transmission vehicles are inherently more efficient, require less maintenance, and are generally less expensive than automatic transmissions, they are usually the choice for larger fleets. Obviously, there are no possible ways to improve performance in a manual transmission, at least not electronically. Fortunately, automatic transmission reap a large number of benefits from performance tuning. Improvements in shift programming can increase performance by utilizing more of the engine's operating output RPM range or "power bank". Reducing slip time between shifts has several benefits including reduced clutch plate wear and minimization of fluid breakdown due to heat. This translates into longer service life, fewer repairs and lower downtime, listed below are the general specifications for the program:

Horsepower Increase: 26% increase for GM Duramax-diesel vehicles

Torque Increase: 38% increase for GM Duramax-diesel

Fuel Economy Increase: (1/2 - 4 miles per gallon avg.) increase for GM Duramax-diesel
