What customers say about the performmaster AMG tuning



Mercedes-AMG GT S

I thought about the possible performance optimization of my AMG GTS for about a year. After detailed research, I decided to use the PEC tuning module. Main reasons: part approval & a complete warranty for engine and transmission – without fuss or quibble. The V-Max delimiter moves the speedometer to over 330km/h. I had the installation carried out directly in Germany. I was impressed by the professional way performmaster took care of my car.



Mercedes A 45 AMG

I am highly satisfied with the Performmaster tuning module!!! The whole package is exceptionally good. For me, the decisive factor was the warranty and the TÜV approval. After the purchase you have an exclusive 1: 1 customer care. Really unique! Top class. I drive my A45 with TOP speed and after approx. 60.000km there are no problems. My conclusion: I would recommend Performmaster at any time without restriction.
