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.)
I’m usually not one for reviews. But this tune is AMAZING. I have had my KTuner v2 for a few months now; using the basemap tunes. I thought it gave my decent power. My buddy told me about the TSP tune and I figured I’d give it a shot…. Let me just say, this tune is BEYOND amazing. The power gain is one thing but I didn’t expect it to make the car drive better as a whole. The rev hang in this car is insane, but the tune takes that away and makes shifting so much smoother. My passengers aren’t moving anymore. My car does get a little hot after some pulls but more power, more heat. Savannah and Kassidy were super helpful with any questions and concerns I had. I will be ordering my next mods from these guys. Absolutely outstanding. Thank you Derek!

Great tune! A lot more powa!
This tune does wonders. If you’re looking for a burst of power that will leave your stock 10th gen friends in shock, look no further. Tsp stage 1 is the tune to go for.

TSP stage 1 for the 17 si is amazing great hp gain and great feel to the car 100% recommend
I've installed many CAI over the years in my vehicles. This was by far the easiest and best fitment one so far. I take my sweet time when installing things because I'm very picky and everything has to be perfect. This intake only took me an hour. To me it looks better and sounds just as good as the PRL intake. Plus the PRL you have to take the ECU out and a bunch of other nonsense when installing it. NO THANK YOU! I highly recommend this CAI for the FL5 Type R.
I'm having a slight issue now that it's installed. I noticed a lil separation from the cover on top of passenger side mirror cover...the carbon fiber is bubbled up slightly and looks like it will only get more noticeable through time. plz advise for solution to this issue.. other than that your products look awesome! I do intend on plenty more future purchases btw, especially if this issue can be resolved with direct attention. Thank you so much and I eagerly anticipate your response even if a replacement cover can be sent to replace this possible defect...
