EZ30R 10psi Supercharged Outback gets dyno tuned on e85, I was not expecting this 🤯

Dyno tune on e85 for about 5 hours. The tuner wasn’t that familiar with this ECU but as you can see he made a lot of progress by the end of the video. 390awhp! I was expecting maybe getting that much at the crank. I’m very happy with my purchase from Raptor Superchargers. #ez30 #subaru #outback #ez30r #supercharged #supercharger #e85 #flat6 #dyno #raptor
