- 2017 Civic Si
This has been in the works for a long time and we are very excited about it! Two Step Performance has partnered with Derek Robinson to offer a high quality Stage 1 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! No supporting mods are required. We also offer support for the PRL Cobra Race MAF housing at no additional charge!
