500+ whp in a COBB/JST Custom Tuned Honda Civic Type R!
Can 500+whp be obtained from a FL5 tuned via COBB Accessport? Why yes it can, and we did it!. It has taken a ton of revisions and a lot of testing, but we were able to make 512 WHP out of our 2024 Civic Type R. To my knowledge this is the first Type R to make over 500whp tuned via Cobb software.


There is a lot more left in the setup (stay tuned for our 2026 Gridlife Time Attack build plans!)
-JST Performance Custom Tune Via Cobb Accessport V3
- PRL Motorsports, LLC Intercooler, front pipe, and High Volume intake.
- RV6 Performance R660 Turbocharger, High flow catted downpipe and front pipe.
-E40 Ethanol fuel blend
-Stock engine, transmission, clutch, turbo inlet and exhaust.
If you are looking into buying a Cobb Accessport and tune for your FK8 or FL5 Civic Type R, or if you already have an Accessport and would like a custom tune, We can definitely help if you just reach out to us. I'll be happy to answer any questions via PM or through email at sales@jst-performance.com. We sell every part listed on this car!
It is 100% worth it to buy a custom tune for your car if you already have an Accessport. The gains are very noticeable, and this will have your car running as safe and efficient as possible.

If you don't already have a tuning device for your car, I would recommend seriously considering Cobb.
