This Volkswagen Golf R got in touch with us for install of the JB4 to match perfectly with the custom made turbo back exhaust (made by exhaust doctor) and the Forge motorsport intake kit.
When testing the car on the dyno in "standard" form (exhaust and intake fitted) we found the hardware modifications added a significant amount of power. As standard these cars produce 380nm of torque, but every one we test makes around 400nm. This example makes more again due to the modifications.
With the JB4 installed we went ahead with our custom map 6 settings after datalogging the car and with intake air temps of 33.4 degrees celsius, the car was more than happy to produce nearly 390 bhp!
