Our 2017+ Civic Si Stage Dub tune is the ultimate solution for your latest drop in 27Won W2 turbo. We put one of Ososik Civics on the W2 turbo and loaded his car on the new 27Won dyno to create the start of this tune (pump gas). Our extensive tuning didn't end there. Ososik took his Civic X to compete in Global Time Attack Finals at Buttonwillow Raceway. After a successful track day with the new tune, we plugged the computer back into the FlashPro to review the data. Then the real fun came, street tuning to develop the tune for flex fuel. This allowed us to get data in real world conditions. Starting from 91 octane, we added ethanol in increments to make sure we can provide you with the best performance out of your W2 (E40-E60 is recommended). Then we put the car back on the dyno to take advantage of Hondata's latest FlashPro Manager software update. 

Dub Tune can only used on a 2017+ Civic Si with:

- 27Won W2 Turbo

- Hondata FlashPro

- Full Bolt Ons

- Flex Fuel Kit


Our flex fuel tuning strategy allows you to run any range of ethanol percentages you desire (91 Oct min), optimizing the full potential of your flex fuel kit but for best performance we recommend E40-E60. Although many have used tunes on a stock motor, we recommend a built motor

***Flex Fuel Kit is Required with this Tune (Sold Separately).***
