Competition use only. This system is sold for sanctioned racing and closed-course use — not legal for sale or use on pollution-controlled vehicles on public roads. Removing or defeating emissions equipment (DPF, EGR, SCR) on a street-driven truck violates federal law. Read the Off-Road Use Policy before you buy.

— // OVERVIEW
TUNED TO SEND IT
A custom transmission tune for the GM T93 (2020-2023). Firmer, faster shifts, raised shift points, and increased line pressure so your truck’s transmission holds power and heat better — especially towing and under load. Delivered as a custom tune file for the AVTOK platform. Requires a compatible AVTOK device (sold separately).
