Daniel B has been a tuning pioneer in the 10th gen Honda community specializing on the Hondata platform. Pushing the envelope and setting milestones with Nicks (Ososik) Civic Si. Daniel has been able to use his knowledge and experience to create stage tunes for enthusiast at all performance levels.

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. 

27Won Tune can only used on a 2017+ Civic Si with full bolt ons:

- 27Won W1 Turbo (https://store.27won.com/2016-civic-turbocharger-upgrade-w1.html)

- Cold Air Intake

- Catless Downpipe

- Intercooler/Charge Pipes

- Clutch

- Flex Fuel Kit

 *Our Stage 27Won tuning strategy allows you to run any range of ethanol percentages you desire, optimizing the full potential of your flex fuel kit. This tune does not guarantee an 11 sec car, because supporting mods, track conditions and most importantly driver mod is needed! Although Ososik (and others) have used this on a stock motor, we recommend a built motor. ***Flex Fuel Kit is Required with this Tune (Sold Separately).***
