Part Number: 30029 Regular Price: $503.95 Ea.

We now have one new part number #30021 for the 2001-2005 GM 6.6L Duramax that we've added our three stages of power tuning to match your driving and towing needs! Stage three being the strongest at +90 horsepower and +150 ft-lbs. of torque for the Duramax! Why the two added tuning options? Diesels, when under heavy loads and for long periods of time, can build up excessive internal heat in engines and transmissions. When that occurs, the check engine light may come on, or flash off and on to warn you that you need to either back off on the power level, or lighten your load. You can't always lighten your load, but now with the Hypertech Power Programmer, you can select the maximum power tuning stage you can safely use under those particular conditions. Why should you use the transmission shift firmness? This option should be utilized when other than stock tuning is in the vehicle. At high boost levels, with higher torque the transmission needs to have firmer shifts...this helps to keep the clutch plates in the automatic transmission from slipping. This is especially true 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!
