The tuning box fitted to my Seat Leon 1.8 DSG transformed the car. As standard it’s a great engine, but the box allowed a great improvement, the car is more responsive, fuel economy is better, and clearly it’s not a placebo perception. All tests has showed me the improvement. Simple installation, great customer care, can’t recommend any other product.
