Wake up your 2004.5-2005 6.6L LLY Duramax with the ADP Tuning EFILive AutoCal Tuner. ADP takes the hassle and guesswork out of custom tuning your truck by providing you with an EFILive AutoCal Tuner to maximize the performance of your diesel engine. The ADP AutoCal Tuner can be configured in a variety of different ways to suit the specific operational requirements and the needs of your truck.
 
HOW IT WORKS: The ADP Tuning EFILive AutoCal will come pre-loaded. After purchase you will be added to the ADP Tuning Community on Facebook where you will have access to our forum with useful information and tips regarding our products. You will be sent an email where you will be asked for information about your truck. This information includes VIN number, modifications and more. Once these fields are filled out and the form is submitted, the experts at ADP will build tuning specifically for your truck. Within 48 hours (business days) you will receive the tunes via email. From there you can load the tunes onto the AutoCal and then into your truck. Each tuner ships with unique information. For this reason, the above process cannot be completed until you physically have the ADP AutoCal.
