Finally sensations on Audi A3 1.5 TFSI 150 HP!

Coming from the 30 TFSI 116 bhp (Audi A1), I wanted to move up a gear by offering myself an almost new 150 bhp A3 1.5 TFSI. What a disappointment! My mechanic explained to me that the difference in acceleration was mainly due to the fact that I had changed from a 3-cylinder to a 4-cylinder and that the A3 was heavier than the A1, but that obviously didn't solve the problem. While doing some research, I quickly came across your box-unit and bought it. I have been driving it for almost 6 months now and I must tell you that I am very happy with it! I have finally found a few good trade-ins worthy of the name. Thank you P-Tronic! Gustav O., Hamar

On Alfa Stelvio Q4 280 bhp: you forget it's an SUV!

I won't hide the fact that the purchase of the box-unit for my Alfa Romeo Stelvio Q4 280 bhp was a whim. The engine is very powerful and gives me a lot of satisfaction. But you know how it goes. 280 hp is good. But the 344 bhp you are announcing is even better! So I let myself be tempted and I don't regret it! Not only has the adapted power become unbelievable, but the torque input makes me forget that I'm driving a suv. I can't thank my friend Sergio enough for talking to me about you. Karl G., Augsbourg
