Tuner Surprised by COMPOUND TURBO SUBARU STI!! (800+ HP)

Today we had the pleasure of tuning a compound turbo STI! Yes you heard it right. As if a single turbo 800+ HP Tubro wasn't enough, they had to add a second Turbo! This crazy build was put together by Simple Performance and brought to us to get everything in good running order. We at Tuned Up have a passion for cars both building and tuning. Join us along for the ride and see what it's like to tune and build some of the craziest cars on the street!
