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.)
This was by far the easiest upgrade to do. Took me longer to jack up the car and take the protective shield off the bottom of the car than it did for this. Defenitely notice an immediate improvement in the way shifting feels.
These are great to add a more premium feel, especially if you like that OEM+ feel and look, but be wary that they will eventually wear out and need replacement, of which the hood stick doesn’t really have a problem with long term usage. Also they bounce when you let go of the hood as u open it up, because of how much force they have pushing against it, so be wary of that.
So, with full bolt ons including catted TSP DP, kuro turbo, complete 3" exhaust, I D intake, PWR intercooler with pipeing, and of course Hondata with custom tune, the final #'s are 379/386 on a hub dyno. No fuel upgrades. Am I happy? You bet I am! A different dyno or tuner could deliver more or less.
