Overview
The 6.2 Silverado is commercially important because truck buyers care about throttle response, transmission behavior, and towing feel as much as peak output. GM changed the security landscape across these years, with E90-based workflows and Global B service requirements shaping how tuning is delivered. That makes this a strong but controller-aware truck product rather than a simple legacy OBD flash.
Key Features
- torque management recalibration
- transmission shift refinement
- towing response
- premium-fuel spark
- drivability improvement

- AMT will read your stock file and flash your custom tune directly on the bench
- Turnaround is typically 3–5 business days from receipt
