Stage 1 for the VF II Holden Commodore with LS3 6.2L V8 involves
reprogramming the factory ECU with HP Tuners VCM Edit Suite software.
This allows Autotech to remap the fuel and timing tables, increasing
torque across the range and improving fuel economy. The auto
transmission can also have its patterns adjusted for more responsible
shifts between gears. Autotech custom tune your vehicle to ensure the
highest levels of performance
