Seat Leon Cupra 290 - JB1 install and dyno

In for installation of the Burger Motorsport JB1 for VAG cars (the latest MQB chassis) was this Seat Leon Cupra which produces 290 bhp as standard. We've performed some testing on these and the stock ECU software matches up near perfectly with that of the mk7 Golf R, but with a few subtle changes. It is these changes we believe that makes the 290 very different to the Cupra 280, Golf R and S3 8V. That said, they still gain fantastic power and mid range torque is incredible as you can see in the graph below.

Power gained: 40 bhp

Torque gained: 54 ftlb
