Cobb Flex Fuel Results on our 2024 WRX
March 12, 2025
The Cobb Tuning Flex Fuel kit makes it possible to run your VB WRX on either pump gas, E85, or any combination there of. We have been looking forward to this option becoming available because there should be be a big jump in performance when we are able to run E85 in the FA24DIT engine.
In this video, we take a look at what comes in the kit, the install, and then we take the car to the dyno to see what the results are.
We have to give a big Thank You to Harvey at The Boostcreep for helping us collect all this data.
Thanks for watching and Stay Tuned!
