Enhanced Performance Options: L5P GM Duramax Tunes (2017-2026)
L5P Duramax tuning provides two powerful choices for your 2017-2026 GM Silverado & Sierra 2500/3500. With the Switch-on-the-Fly (SOTF) tunes (2017-2023), you can instantly switch between five different power levels while driving, tailoring output to any situation. For newer models, our Single Calibration tunes (2024-2026) deliver consistent power gains with a dedicated performance map. Both options are designed to help you unlock more from your truck while maintaining smooth drivability.
Perfect for drivers seeking flexibility in earlier model years or a straightforward performance boost in the newest trucks.
