Existing TSP Stage 1 Si/Integra tune owners can use this product listing to upgrade to our new Stage One+ tune at a discounted rate! This is eligible to anyone that has purchased the TSP Stage 1 tune directly from us, either as a standalone tune or with a KTuner unit. This will be verified before the order is filled.

**KTuner only! Due to boost control issues with Hondata's 11th gen 1.5T software, we are not able to offer this tune for Hondata.**

Are you looking for the highest level of safe power output from your 22+ Civic Si / 23+ 1.5T Integra? Look no further!

Two Step Performance continues to partner with Derek Robinson to offer an even more powerful tune for the 2022+ Si. The tune offers peak power gains of 38 whp and 97 ft-lbs of torque in comparison to the factory ECU calibration! Full details are as follows:

192whp / 190tq - Factory Calibration
221whp / 251tq - TSP Stage 1 Tune
230whp / 287tq - TSP Stage One+ Tune

All testing was completed on a FBO 2023 Civic Si running 93 octane fuel. Tune features include:

  • Numerous fuel, ignition, turbo response, throttle response changes.
  • More aggressive tuning strategy compared to original TSP Stage 1, allowing for more midrange and top-end power.
  • Increased warm idle speed to eliminate vibration from aftermarket mounts.
  • OEM/Standard/Street MAF and PRL Motorsports Race/Big Bore MAF support (select appropriate option)
  • WOT shifting enabled. (Set to 5000RPM)
  • Adjustable launch control enabled.
  • "Rev hang" disabled with soft throttle padding (user adjustable)
  • Several tweaks to smooth the feel between gear shifts.
  • All disables / monitors are able to be adjusted by the end user.
  • Quick Boost By Gear is able to be adjusted by the end user.
  • On-the-fly boost map switching active for normal and "Sport" modes. (see below)
  • Throttle Responsiveness & Throttle Padding Settings are allowed to be adjusted by the end user so that the overall feel can be aggressive or more toned down, as desired.

Factory boost level in "Map 1" allows for easy "valet" mode when the KTuner unit is unplugged from the car! 93+ octane is REQUIRED. Use of lower grade fuels is NOT tolerated and will result in power loss. 100oct race gasoline is suitable, as long as it does not contain lead. The calibration will support up to about 15% ethanol content if necessary to increase knock resistance. For example, you can blend approximately 1 gallon of E85 with 91 octane to achieve the knock resistance required to safely and effectively use this tune.

Upgraded clutch REQUIRED, and an upgraded intercooler is highly recommended.

Suitable for use with the factory intake or a QUALITY aftermarket intake that keep fuel trims in check such as the PRL High Volume Intake. Aftermarket downpipes are also fine. Mods such as this are expected to add power that is not accounted for in our dyno testing.

*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.*

This tune is for the 2022+ Civic Si & 2023+ 1.5T Integra 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.) 

Please verify that your ECU is supported via our TSP Tune Compatibility List prior to purchase. Click here for our installation guide.
