DIESELR Tuning (2022-2024 6.7L Cummins)
What's included?
This is a DieselR release for 22-24 Cummins. Consumers need to understand that these trucks are not easy to tune and can take up to 7-10 Business days before they are fully dialed in after multiple revisions and require a PCM to be swapped into the truck. SOTF tuning works on 90% of trucks tuned however it does not always work. If a consumer purchases SOTF and they are one of the unlucky few with a truck that does not have OS options currently available for SOTF tuning, they will receive a single tune only and will not be refunded for the SOTF cost. There is no way of knowing what trucks may be affected until the tuning process has started. As this is a BETA release, tuning is done at the consumers own risk!
We strongly recommend having this done by an authorized dealer that is able to perform PCM swaps and factory OEM calibrations. In the case of a bricked PCM scenario, dealers may be required to flash the PCM back to factory using OEM tooling. No refunds once purchased, pay to play and do it at your own risk!
