“The KTuner V1.2 paired with the TSP Tune breathes new life into the 1.5T engine and completely changes the driving experience. The kit comes nicely packaged and the interface is easy to use. The V1.2 can be paired to compatible bluetooth devices running the TunerView app for useful data displays and customizable layouts. The real gem of the package is the TSP Tune itself; specifically the 3 driving modes/maps included. From your vehicles steering wheel controls, you can easily switch between maps on the fly. I've tested each map extensively during city, highway, spirited mountain passes and even a few laps around my local race track. I must say, I am beyond impressed by the smooth power delivery and the rush of power from the added boost. The vehicle felt much more responsive and optimized across the entire rev range and it's very obvious that a lot of effort was put into these tunes. The fact that Two Step Performance includes this tune with the purchase of a Tuner unit makes this purchase a no brainer. If you have a 10th generation Honda Civic, and you want to enjoy it's true potential, you need to invest in this package!”
