2017-2019 Duramax 6.6L L5P Complete Package

2017–2019 Duramax L5P Complete Package

Choose your model year, SPS exhaust and tuning platform for your Chevrolet Silverado or GMC Sierra 2500/3500 6.6L L5P pickup.

Included in Every Selection

• Your chosen SPS aluminized exhaust: 4-inch race pipe, 4-inch downpipe-back or 5-inch downpipe-back, with or without a muffler.
• SPS 800011 L5P cooler upgrade kit.
• L5P-ELC-A180 CAN bus plug kit.
• The tuning files and device for the platform selected below.

Peakside / HP Tuners

Every HP Tuners selection includes Peakside single or SOTF tuning and six universal ECM credits. 2017–2018 includes an MPVI4 device; 2019 includes an RTD4 remote tuning device. SOTF uses the factory cruise-control buttons; a separate manual switch is not included.

2017–2018 unlock kit option: choose a tuning selection marked “+ Unlock Kit” to add the E41 ECM upgrade tool (ECM-00-L5P-K) for $293.25 USD. The kit is not included in the other selections. A locked 2017 ECM needs the appropriate upgrade before tuning. Supported 2018 controllers also have a direct OBD upgrade option. The kit is a tool, not a replacement ECM or a completed unlock service. The 2019 RTD4 selection uses the supported direct OBD upgrade and does not include this kit.

Peakside / EZ Lynk

Includes an AutoAgent 3 and Peakside single-tune support for four weeks or lifetime. These selections do not include SOTF.

2017–2018 Peakside/EZ Lynk requires a previously unlocked, supported ECM. An ECM unlock service and HP unlock tool are not included in EZ Lynk selections. Confirm ECM part number and unlock status with us before choosing this platform.

Fitment and Order Details

Provide your 17-character VIN, model year, ECM part number, cab, bed, wheelbase and current modifications before fulfillment. This package is for L5P pickups; cab/chassis and L5D applications require a separate fitment review. Transmission tuning, a modified TCM and TCM credits are not included. Component photos are examples; the exhaust and tuning hardware supplied follow your selection.
