Description
Overview
The DiabloSport Chevrolet, GMC (6.6) Computer Chip Programmer is a breakthrough tuning solution built around the industry-leading Trinity T2 on-dash tuner. Designed for 2020–2023 GM 6.6L L8T gas trucks, this complete kit finally gives owners the ability to unlock performance in a previously restricted platform. If you’ve been searching for a real path to more power on the L8T gas engine, this DiabloSport programmer delivers it in one comprehensive package.
Because these late-model GM ECMs ship locked from the factory, the kit ships with everything required to get you tuning. Along with the Trinity T2 tuner, you receive the required locksmith device and harness needed to unlock your truck’s ECM — no guesswork and no chasing down extra components to complete the job.
Key Benefits
At the heart of the kit is the Trinity T2, a color touch screen tuner that mounts on the dash for true in-cab monitoring. Load performance tunes to wake up your 6.6L gas truck, then keep an eye on everything that matters while you drive. The bright color display features an auto-dimming screen, so critical data stays readable in daylight and won’t overwhelm you at night.
The Trinity T2 is far more than a simple flash tool. It functions as a full-featured gauge monitor and diagnostic device, with data logging, alerts and records, and built-in performance tests so you can measure results and track your truck’s behavior over time. Video-capable operation and Wi-Fi updates keep the device current and versatile, while 5-volt data logging inputs and a digital speedometer round out the monitoring capabilities.
