My Mercedes GLC 250 4Matic was optimized, and I have to say — this old man can't help but smile behind the wheel. The torque is unbelievable, and the fuel consumption dropped from 6.3 to 5.4 liters despite winter tires and winter conditions. QT Performance handles their work professionally and quickly. The service is polite, flexible, and truly respectful toward the customer. .

Excellent customer service. Positive guys as entrepreneurs. I was left with a really good feeling about this company. Both the car and the owner were happy. Can't do anything but recommend 👍

The Audi A8 gained over 60 horsepower and an extra 100 Nm of torque.

During a long trip at Midsummer, the fuel consumption was indeed lower as promised, even with the air conditioning blasting.

Strong recommendation 💪👍👏!

I was referred to them by a British performance company with questions about my Brabus software and performance upgrade. The company representative walked me through the process and clearly explained the weaknesses, what can be done, and what cannot. I was able to make an informed decision that a performance upgrade is necessary, and I will be choosing them for it. I highly recommend them to others as well.

My 2013 BMW 318d turned into quite a missile — I no longer need to keep my finger ready to switch to Sport, because even in Comfort mode the tuning made both the engine and the automatic transmission work together extremely well. All my future cars will be coming here — it moves! 💪

Kari Laari

The character of the engine improved significantly, and the increase in torque is clearly noticeable while driving. Fuel consumption also dropped by almost a liter. Nothing but positive thoughts from me.
