Data Logging, Expandability, and Legal Compliance
In addition to performance tuning, this system includes built-in data logging, Wi-Fi updates, and support for custom tuning adjustments as your build evolves. Moreover, the CTS3 platform can be expanded using the optional EAS system or EGT Probe Kit, allowing you to monitor additional parameters as needed. Best of all, the KC Turbo CTS3 Evolution Tuner remains 49-state legal, ensuring compliance while still delivering meaningful performance gains.
Injector Compatibility Information
