“Amazing product. With the stage 1 tune the si drives like an entirely different car how a si should drive. Eliminated the annoying rev hang and much more power in the mid and upper ranges.”
“This product is very easy to use and works great! It adds a nice little punch to the car and makes it really fun to drive! I also got slightly better MPG with the TSP Stage 1 tune. The difference is day & night and the on fly switching works flawlessly!”
“I'm loving my ktuner it has made so much of a difference already. Once I get my downpipe and intake from PRL I'll be able to use the TSP stage one tune.”
“I always thought the civic si was underpowered from the factory. I wasn’t impressed at all with power the first 18,000 miles so turned to KTuner and saw a lot of good things about the tsp tune. It changes the car completely and now it drives like it should’ve from the factory.”
“Love this tune. Very easy to use and plenty of resources available online to help get an understanding of the installation process. Couldn't be easier! Basically plug and play. The inclusion of the TSP Stage 1 Tune was icing on the cake and the reason I purchased from Two Step Performance. The included TSP sticker is already on my car!”
