Join the over 3500 10th Gen Civic Si owners that have elevated their Si to another level with our Stage 1 Tune!
Two Step Performance has partnered with Derek Robinson to offer a high quality tune for the 2017+ Civic Si that offers an additional 55 whp and 76 ft lbs of torque in comparison to the factory ECU calibration. Full details are as follows:
Factory boost level in "Map 1" allows for easy "valet" mode when the KTuner unit is unplugged from the car!
Premium fuel (91 or 93 octane) is REQUIRED.
Suitable for use with the factory intake or a QUALITY aftermarket intake that keep fuel trims in check such as the PRL Motorsports Cobra. Aftermarket downpipes are also fine. Mods such as this are expected to add power that is not accounted for in our dyno testing.
In addition to standard sized intakes, the PRL Race MAF Cobra & Short Ram intakes as well as the 27Won Race MAF intake are supported. Please select the appropriate option for your intake when ordering. Need to make a change later down the road? Take advantage of our File Conversion Service.
*Tune orders placed during business hours are typically fulfilled via email the same day. Orders outside of business hours are filled the following business day. FlashPro tune orders may be slightly delayed due to the process required to build your custom file.* Hondata FlashPro users should also notethat we are NOT offering a secondary O2 disable service for this tune, which means you are not able to use this tune with a downpipe that does not meet emission standards.
This tune is for the 2017+ Civic Si only. Please be sure you are purchasing the correct tune for your vehicle because digitally delivered items are non-refundable. (If you buy this for your 2016 Civic LX, it won't work, and we cannot offer a refund.)

Granted I am new to modding cars and this had to be the 3rd mod I’ve ever purchased for my 24’ Integra A-Spec.
Before Ktuner, I had a PRL Ram Air Intake and a resonator delete for my exhaust system.
I had purchased this and went through set up, Ktuner software connecting to their servers may be really bad but once you troubleshoot how to get the application working, downloading the prepared tune, and applying,I can tell you the turbo has gone more responsive, the rev hang is gone, and my favorite- the auto on/off engine feature is permanently disabled. Just when getting in my 6-speed was starting to feel boring, this really sparked me to try new things. Fast forward I became a repeat customer for TSP giving me confidence this retailer knows Honda/ Acura well, I got my first exhaust mod- an upgraded downpipe! With the pops and bangs tune that was available on Ktuner thanks to TSP’s free tune, the downpipe and resonator delete worked better in my favor than ever before, making the Ktuner the one stop in Si/ a-spec tuning thatyou wouldn’t want to skip.
My Accord looks way better with the chrome delete. I went with Satin and have no regrets. This product is great however it requires patience when installing. Speed is your enemy here so take your time and go slow.
