Product Details
2024–2026 GM and Chevrolet L5P Duramax tuning utilizing HP Tuners.
Single tune only. Choose one power level: 0 HP, 50 HP, 100 HP, 120 HP, or 180 HP. No SOTF or TCM tuning is available for this kit.
Eight HP Tuners ECM credits are required and are sold separately as an optional add-on. An HP Tuners interface is required; add an MPVI4 if needed.
An E42 ECM unlock service performed by HP Tuners is required before tuning. Add the unlock service and round-trip next-day-air shipping, or decline if you already have an HP Tuners-unlocked ECM or will arrange the required service separately. The unlock service requires shipping your ECM to HP Tuners.
Optional CAN bus plugs are available for 2024 and 2025. No 2026 CAN bus plug is currently available. Select accessories matching your vehicle and confirm fitment before ordering.
Provide your VIN, vehicle details, MPVI4 serial number, and modifications to complete your tuning order.
