Our 10th gen Civic Si Stage 27Won tune was a result of being part of the @27Won W1 drop in turbo development process. We put Ososik "Si Se Puede" Civic through hours of dyno time, extensively testing the W1 turbo from a wide array of power and ethanol levels before becoming the worlds first 11 second (1/4 mile) 10th gen! This tune has had thousands of daily commute miles in the most extreme conditions and has been refined throughout the years utilizing Hondata's latest software features.
