McLaren GT — Engine Variants & Typical Gains
Every McLaren GT file is developed from the vehicle's own stock read and your declared hardware, then refined against your data logs using OEM ECU and the major flash platforms.
| Engine variant | Power (stock → tuned) | Torque (stock → tuned) |
|---|---|---|
| 4.0 V8 620hp | 620 → 819 hp | 630 → 880 Nm |
Tuned figures are typical estimates from this model's gains; actual results depend on variant, fuel and supporting hardware, and are verified from your logs.
