Tuning

What is Tuning

Custom tuning allows you to adjust many engine and transmission parameters. Most customers tune for better fuel economy. By changing the combustion rate and removing EGR gases (if possible), you get more energy from fuel, leading to better mileage and more power.

Single Tune

The single tune is ideal for those seeking a mild tow or economy tune and don't need to switch tunes. The truck runs like with a stock tune, suitable when multiple people drive the truck. We can customize it to any power level.

5 Tunes

The 5 - tune option is perfect for adjusting power according to your needs. For example, you can increase power when the truck is empty and reduce it when towing to ease stress on the drivetrain.

Power Levels

Different power levels can be customized based on your request and vehicle modifications. Here's a general idea:

• Level 1: 20 HP
• Level 2: 50 HP
• Level 3: 120 HP
• Level 4: 175 HP
• Level 5: 200 - 230 HP

VIN License & Link Codes

To buy an EFI Live Vin License, you need your device's serial number and authorization codes. If using an Autocal Device, it must be linked to our tuning service. If it was previously linked to another provider, get unlink codes and unlink it first.

Installation

Using this product is a great way to enhance your diesel pick - up's performance. First, when it comes to installation, if your truck already has tuning, reach out to the previous tuner for AutoCal Unlink Codes and follow their guidance. Then, download the latest EFILive V8 and update your AutoCal Device's firmware. Provide us with your AutoCal Serial Number, Auth Code, and VIN Number. You can find the Serial Number and AuthCode in F7 Licences - F3 Vins. There are different tuning options. A single tune is easy - going, suitable for those who just want a simple, set - it - and - forget - it option, like for mild towing or better economy. The 5 - tune option gives you flexibility to change power based on your needs. Different power levels are available, and we can customize them according to your requests and vehicle modifications. As for VIN License and Link Codes, make sure you get your device's serial number and authorization codes. If your Autocal Device was used by another tune provider before, get unlink codes and unlink it from that company. Also, remember this product only includes tune files.
