I had John (Visconti Tuning) come out and tune my car yesterday. My car is bone stock and I wanted to see how it would feel with the STG1 Ecutek. Car runs really good now, I always felt a little hesitation in the higher rpms but I feel a nice difference in the mid to higher rpms. Clean power all the way through redline, which was also raised a bit. I am very happy with my tune and my car. John is a very professional guy, arrived at my house right on time and was able to do my tune on the spot with no notice. Initially he was just coming over to ensure his system was compatible with a 2013. I had my brother take my car out for a ride (he also has a 2013 370Z) and I didn't tell him I did the tune, when he got back he instantly asked me if I did anything to the car because it feels better than his. I definitely recommend the tune!!!!
Thanks to John @ V-Tune
