Like the BMW M140i we posted about earlier, this was the first JB4 to be fitted to the Volkswagen Polo GTi. This example was the manual which already comes with a huge 68 NM of torque more than it's DSG counterpart, but gives us a lot more head room when it comes to tuning. As well as being up on torque, the car produced a staggering 213 bhp when standard! Volkswagen claim the car to be 190 bhp.
As you can see from the graph below, the power and torque delivery is now much smoother with the mid range torque dip completely flat now.
Power gained: 46 bhp
Torque gained: 65 nm
