Out of the box the twin turbo V6 is good for 272kW or 370HP and will run a high 12-second quarter mile from the four door AWD family saloon. HP-F (The Horsepower Factory) in Dandenong is now offering custom ECU remapping for the Kia Stinger. We took a look at two different modified GT examples and their dyno tuning results. Leave a comment
