2010 Subaru WRX STI in World Rally Blue being tuned on a Dynotuner


Here we have a 2010 Subaru Impreza WRX STi that was custom tuned by TurboTek Tuning; with a COBB Intake & Airbox, 3″ Catted Turboback exhaust, 1050x Injectors, and IAG TGV Deletes among other modifications. With the addition of a built short block we’re able to run the car a little bit leaner without any risk and gain a good amount more power over a stock motor. With a stock STi making around 230WHP this car made a beautiful ~85WHP gain – The addition of these simple upgrades along with tuning made this all possible.
