“I purchased KTuner V1.2 and free TSP stage 1.
Coming from other "wifi exclusive" devices (send, receive, load tunes over wifi) I was worried maybe using the computer to do everything might be a learning curve at first... Nope, easy as can be.
This is how the car should be from the start. Woke my 2017 civic Si up. Just need a new clutch now, slips pretty good in Map3 if I don't REALLY roll in the power.
Definitely would recommend.”
“Purchased ktuner v1.2 for my 18’ si. Great deal since it came with the free tsp stage 1 tune. Shipping was fast and the tune is amazing. Really woke the car up! I will be purchasing more products from two step performance in the future. Choose these guys first. You won’t be disappointed.”
“I kept making excuses to myself and talking myself out of buying this product. Even bought it and immediately cancelled it once. Well I finally pulled the trigger and I should have bought this a year ago. My car has 78k stock miles on it and I've been missing out. Make sure you use the tune TSP provides”
“Tune is great, can definitely tell the difference. Mostly bolt ons, have the base map loaded up but can feel the difference when driving. Spool is quicker and better plus less rev hang is amazing. Shipping came quick so i’m satisfied”
“This is the best thing I have bought for my car since having it. If I knew how good it would be I would have bought it sooner. The Stage 1 tune is amazing. No regrets with this purchase.....”
“Ktuner product is amazing, and the TSP stage 1 tune is AWESOME. Love how the car produces specific amount of boost and throttle response for the CVT. Customer service was great. And these guys are always here to help. Defnitely will do future business with two step performance.”
“The KTuner base maps themselves makes a huge difference and makes the car feel phenomenal. Pair that with the ability to run the TSP tune is a game changer. The TSP tune is by far one of the best tunes out there for this platform. If you have any additional mods on you car you will want to look into upgrading your clutch at the same time though. Overall opinion, this is the best mod you can get for a 10th gen si.”
