Why upgrade to Custom Tuning?

Switch-On-The-Fly Tuning for Your L5P!

2017-2023 L5P Custom Tuning

Unlike box tuners, our tuning can be designed to take into account other modifications like upgraded turbos, aftermarket intakes, and built transmissions. Tuning with these upgrades in mind can also help improve the performance gains seen from these modifications. Precise fuel and timing adjustments mean less unburnt fuel than box tuners. This results in less soot out the tailpipe, less DPF accumulation, longer intervals between regens, and less wasted fuel. Your tunes will also be optimized to work with your 6 or 10-speed transmission. Plus we have the ability to tune your 6 or 10-speed transmission. Providing even better performance from your ECM tuning and improving your transmissions ability to hold power.

  • Increased Power Holding Capacity

    • By electronically increasing your transmission's line pressure through TCM tuning we can improve your transmissions ability to hold power. This is a must in terms of making your transmission capable of handling all 595hp that custom tuning can provide. 

  • Improved Power Delivery

    • Our improved torque converter lock-up strategy enhances performance by minimizing  converter slippage. Ensuring a more efficient power transfer from the engine to the transmission. This results in better acceleration and throttle response, as well as improved fuel economy

    Optimized Shift Points
    • While ECM tuning has the ability to broaden your power band across the entire RPM range of your engine. Your stock transmission tuning likely doesn't allow your engine to rev out far enough to take advantage of this. Thats where TCM tuning's optimized shift points come in. By increasing your shift points you will gain access to more of the additional power provided by your ECM tuning.

  • Improved Power Delivery

    • TCM tuning gives us the ability shorten the time it takes for your transmission to change gears. What this means for you is less dips in power across your entire plane of acceleration and higher average power levels making it to your wheels.

  • 6 Speed Allison TCM Tuning 

    The 6-Speed Allison found in your 2017-2019 L5P Duramax earned its reputation for excellence largely because of the advanced electronic control provided by the TCM (Transmission Control Module). Changing that factory calibration is especially important for you when you modify your truck and/or install ECM Tuning. Custom TCM Tuning gives you quicker shifts, smoother operation and an overall a better driving experience.

  • 10 Speed Allison TCM Tuning

    The 10-Speed Allison found in your 2020-2023 L5P Duramax is known for its smooth shifts and great performance while towing. However, it still leaves a bit to be desired when it comes to shifting in high-performance scenarios. It can struggle to keep up due to its constant drawn-out shifts and its weaker clutch-holding strength. Changing the factory calibration is especially important when you modify your truck and/or install ECM Tuning. Custom TCM Tuning gives you quicker shift changes, smoother transmission operation, and an overall better driving experience.
