Installation Recommendations of L5P Delete Kit
Installing the DynoVox EGR/DPF Delete Kit on a 2017–2023 6.6L L5P Duramax requires mechanical expertise and the appropriate tools. For best results, we recommend having the installation performed by a certified diesel technician, although experienced enthusiasts may complete the process themselves.
Before starting, ensure the vehicle is parked on a level surface, the battery is disconnected, and the engine has completely cooled. It is important to review all components in the kit and confirm compatibility with your vehicle model and year.
The installation involves removing the factory EGR valve, EGR cooler, and DPF system. Once these components are removed, the provided block-off plates, pipes, and hardware should be installed according to the included instructions. All connections must be carefully checked to ensure proper alignment and secure fitment.
Installation typically takes between 4 to 6 hours, depending on experience and equipment. After installation, inspect the exhaust system for leaks and confirm that all sensors and wiring harnesses are either properly reconnected or securely capped.
ECU Tuning Required
After installing the delete kit, ECU tuning is essential to prevent error codes, limp mode, or performance issues. A compatible tuner must be used to disable EGR/DPF-related codes and recalibrate engine parameters. Proper tuning ensures your 6.6L L5P Duramax runs smoothly, efficiently, and at peak performance.
Upgrade your L5P Duramax with the DynoVox EGR/DPF Delete Kit and unleash the full performance your truck was built to deliver.
