In for our CustomPro remappings software was this Volvo S60 which has the D3 2.0 turbo diesel engine with 136 bhp as standard. These cars tune brilliantly and drive really well once tuned thanks to the improved throttle response and additional low down torque.
As you can see from the dyno graph below, power and torque are both introduced a lot earlier, but also held for much longer and the difference is night and day.
Power gained: 46 bhp
Torque gained: 51 ftlb
