“Ran ktuner base maps for a couple of days and was pretty happy with the result. Was hesitant to flash their tune because the massive torque gain worried me but after a couple of emails with Corey, my insecurities went away. Car handles the tsp stage 1 tune beautifully. Even makes ktuners 23psi tune feel like stock. I’m happy with the tune but I’m even more happy with twosteps support staff. Two thumbs up!”
“Purchased this for my 2020 Civic Si and all I can say is wow! First of all, fastest shipping I think I've ever had for a car part haha.. I've had experience with KTuner in the past on different applications, but with this particular car the KTuner REALLY wakes it up. My favorite part though is having a device to store tunes on (hint hint TSP Stage 1) and view real-time information, it's really nice to not need a laptop for everything!”
“I was scared about figuring out how everything works but it’s extremely easy to use and to figure out all the options you have. The TSP Stage 1 tune is amazing. A lot of power and response really opened up the power. The power band and how it holds boost is amazing. Still have great MPG too.”
