If you’ve recently upgraded your fuel system, swapped out your turbo, or performed any other LML Duramax upgrades, then your truck needs tuning. The LML Duramax mods you have made run differently from stock parts, so you have to adjust your engine’s tuning to get the most out of them. Modern vehicle tuning doesn’t involve adjusting a bunch of screws and bolts. Instead, it’s all handled by the vehicle’s ECM. You can either take the vehicle to a shop and have them tune it for you or purchase an LML Duramax tuner and tune it yourself. +Read more
An LML programmer may be one of the best investments you can make. The costs are often equal to, or less than, paying a shop to tune your vehicle. The best LML tuners are also designed for ease of use, which should reduce the learning curve if you’ve never tuned a modern truck before. If you buy your own tuner, it also makes future post-tuning modifications and tweaks essentially “free” too.
You don’t need to have recently upgraded your truck for an LML tuner (also known as an LML Duramax chip) to be useful. Stock tunings tend to be a little on the “safe” side and are designed for all-around functionality. You can likely adjust the tuning of an unmodified truck and eke out a good amount of extra performance. You can also “specialize” your truck to some extent. Things like towing, off-roading, and long-distance driving have different demands, and individual tunings will make sure your vehicle is optimized to meet those demands. Tuning files can be saved on an external device, allowing you to switch between them easily in the future. While there are budget tuners available, opting for the best LML Duramax tuner is unlikely to cost you much more and will provide a lot of extra functionality and usability.
