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 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.
