Why are there three stages of power tuning for the diesel engines and why do you recommend using the transmission feat ure?
Diesels, 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 stack you can safely use under those particular conditions. Why should you use the transmission feature? The transmission feature allows the automatic transmission’s shift firmness for increased line pressure. 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. For everyday use, it isn’t as critical.
