Turbo upgrades are a way of upgrading the engine performance of your Seat Leon 1.8 T AQA / AJQ 150HP. With the help of our ECU tuning files, you can make your car go faster and smoother than before.
Turbo upgrade involves changing the exhaust system, intake system, and more importantly, modifying the engine control unit (ECU) file of your Seat Leon 1.8 T AQA / AJQ 150HP. The ECU is what controls how much fuel is injected into the cylinders and when it's injected. It also controls how much air is allowed in through the throttle body.
