We now have two new part numbers for the Ford Power Stroke 7.3L diesel (part #41040 for 2001-2003 and part #41039 for 1999-2000). There are two additional new diesel releases: Part number #30021 is for the 2001-2004 GM 6.6L Duramax, and #50009 is for the 1998 1/2-2002 Dodge Cummins. To all of these, we've added our three stages of power tuning, each designed to match a range of driving and towing needs. Of these, Stage Three is the strongest. For the Powerstroke, this stage provides an additional 100 horsepower and 164 ft.-lbs. of torque, with plus 90 horsepower and 150 ft.-lbs. of torque for the Duramax!

When operated under heavy loads and for long periods of time, diesels can build up excessive heat in their engines and transmissions. When that occurs, the check-engine light may come on, or flash off and on, as a warning to either back off on the power level or lighten the load. While you can't always lighten the load, Hypertech's three-stage tuning lets you select the maximum power tuning level that can be safely used under high load conditions.

This should be used when non-stock tuning is in the vehicle. At high boost levels and higher torque, the transmission needs to have firmer shifts. This helps keep automatic transmission clutch plates from slipping, especially important when towing heavy loads.

With the new Power Programmer and the 3 Stages of Power Tuning, you'll have more control over driving and towing conditions than ever before!
