The HSV GTS is based on the Holden VF Commodore and it is a sporty sedan. It is equipped with a 6.2-liter LSA supercharged V8 that produces 577 hp and 740 Nm. Walkinshaw Performance though decided to present a tuning package for the car to make it even more powerful.
They launched on the market the W507 package, which equips the car with a new air intake, new exhaust and a reprogrammed ECU which help the engine deliver 680 hp and 850 Nm of torque. This package is available for order and according to the tuner, they have already collected 200 orders for it. Which seems very logical, since for the 7990 AUD that the package costs, the customer acquires a increase of 103 horses, 110 Nm torque and a guarantee for the mechanical parts of the car, which makes the package a value-for-money bargain.
