You'll notice the torque, esp in a heavy SUV
I have a 2018 Tiguan 4MOTION. This little device was easy to install. I had to remove the plastic shield under the engine to access the boost sensor plug. You will notice the power, esp the torque. I would say it took about 30 miles of driving to feel it's true potential -- but now my Tiguan has the right amount of power I had wished it came from the factory with. Still gets same gas mileage when driving normal.
