What We Tune
✔️ Stock & modified setups (intakes, headers, exhaust, etc.)
✔️ Cammed engines (Stage 1 & 2 work great; Stage 3+ may need dyno tuning)
✔️ Transmission tuning included for 4L60, 4L80, 4L65, and 4L70 (firmer shifts, torque management, speedo recalibration) but you must send the T42 controller if you have a 2007+ vehicle (or you can just get engine tuning)
