The Seat Leon 1.4 TSI 150 hp becomes a real sports car

I am a VW customer, and this is my first Seat. I drive less than 15,000 km/year. I chose this little 1.4 petrol turbo with 150 hp. My first thought was that the engine is much nicer than my previous 1.6 TDI. I had tested the 1.4 in an Audi Q2 and I got the impression that they had changed the engine mapping in my Leon. It's much too linear for my taste. I'm 62 and I wanted some fun when I bought this car. By adding a P-Tronic external reprogrammer (my fourth), my car has become much more agile and alert. The DSG gearbox is perfect. I miss the paddles. Conclusion: my TSI with the P-Tronic is the choice for a real sports car! Vinko K, Dubrovnik (Croatia)

My Opel Vivaro has got its wind back

My Opel Vivaro was a bit dodgy where power was concerned, especially when loaded. With the P-Tronic kit, it's got its wind back, especially on hills. And there's more torque too, which I especially appreciate when I'm driving in town.   Christophe G., Verviers.
