“Got my ktuner about two weeks ago and I’ve been loving it! I flashed the TSP Stage 1 tune on to my car and it really woke up the car! Definitely no regrets about buying this product”
“The product came within the promised 2 days and I've had no problems since installing. Overall great purchase and the TSP Tune makes a huge difference.”
“Ktuner is 100% the way to for the 10th gen civic. I have the si and with my order I also got 2 day shipping and the tsp stage 1 tune. Ktuner came in 2 days and the stage 1 tune made the car feel twice as fast as stock. I use map one most of the time and map three sport mode when I want to really have fun. 100% worth it, no contest.”
“I think the unit itself gets a little hot in the sun but other than that it's an absolute pleasure too have it installed on the car! The performance is absolutely 10x better than it came from the factory!”
“KTuner V2.0 is a great tuning device, and getting the TSP Stage 1 tune bundled with it for free should make purchasing it a no-brainer. The TSP Stage 1 tune is fantastic for all Civics from stock to FBO. This is arguably the best modification you can make to your 10th gen Civic. There's a ton of useful documentation out there for KTuner as well, to help get you acquainted if this is your first foray into tuning.”
“2018 Civic Si: KTuner with the TSP Stage 1 tune is amazing. Very easy to use. Noticed a huge difference in rev hang. Shifting from 1st to 2nd was no longer a chore. Increased boost levels was nice. Can definitely tell a difference.”
