We had something very special in recently for our CustomPro remap and installation of the Larini resonator delete system. The owner of this Bentley Continental GTS-C has brought around 6-7 previous cars to us for work, the latest purchase being this. The car was no means slow when it was standard. It uses the 4.0 TFSI twin turbo V8 so it also sounded brilliant, but the owner complained the sound was "muffled", and we agreed.
After we installed the Larini "H-pipe" system which removed the centre resonator the car came alive. It was no longer a muffled V8 noise, but more of a roar, especially at 6,000 rpm +
With the exhaust complete the car was strapped to the dyno so we could begin tuning it with out CustomPro remap software. The owner would have been disappointed with anything less than 650 bhp and 850 nm so that was our target. You can see how we got on with the graph below:
Power gained: 140 bhp @ 5,400 rpm
Torque gained: 160 nm
