We offer multiple options for delivering your custom tune to ensure the most convenient and efficient experience for you:

  1. Email Delivery (EFI Live AutoCal or FlashScan Owners): If you already possess an EFI Live AutoCal or FlashScan, we can email the custom tune file directly to you. Please note that you will need to have your AutoCal unlinked from any previous tuner. We are available to assist you in this process.

  2. Pre-loaded AutoCal Purchase: If you do not have an AutoCal or FlashScan, you can acquire one through us, and we will pre-load your custom tunes onto the device. This option minimizes truck downtime and simplifies the process.

  3. Bench Flashing Service: You may opt for our bench flashing service, where you send us your ECM or TCM for tuning. This is a cost-effective alternative to purchasing your own hardware. We offer same-day turnaround times for this service to reduce truck downtime. After placing your order, you will receive an email with shipping instructions.

Regardless of the method you choose, all our sales include comprehensive remote support and unlimited free updates, unless you decide to upgrade to non-VGT, twins/compound setups, or injectors with a 30% increase in size.

Please be aware that AutoCals may experience high demand, and shipping may take 3-5 days. TCM tuning is provided at no extra cost when you opt for ECM bench flashing. If you wish to have your TCM tuned as well, simply ship it with your ECM.

Warning: The LLY E60 controller is known to have a high error rate during flashing. They may require specific fuses to be pulled. We will provide this information below, but we highly recommend bench flashing these controllers for a smoother and more reliable process.

2005 LLY Duramax

Had a custom tow tune programmed from here for my 2005 LLY and am very impressed with the results! They were quick to answer any questions and turn around time was quick. I would highly recommend their tuning!

Amazing company

Everyone at Tennessee Tuned was so awesome. I shipped in my ECM and tcm to get programmed and tuned and within 2 days it was in the mail already coming back. They kept me updated the entire process. Once I put my ECM in I could tell the difference in power and even shifting in the transmission.

I can’t recommend these guys enough.
