GAN reviews from Porsche 911 owners

Advantages: Simple and convenient. Satisfied with result.

Comment: I connected this device via the attached cable and hid it behind the pile floor covering. Up to 100 km, I notices the result: the throttle response at 1,2,3 gear is better, the fuel consumption did not change (I use the “Dynamic” mode). I think the result is good for such kind of tuning. I like my car more.

Advantages: Simple installation, it really works, fuel saving - more than 1L/100 km, mobile App works perfectly in the city and outside! The car became faster. Gear changes also became faster. In the cabine it is much quieter due to the reduction of revs.

Disadvantages: I haven’t noticed yet!
