Bentley Continental having our 680 conversion and exhaust mods.
This GTC was fairly pokey with the 572bhp from the factory but now running secondary cat delete and a tune is pushing out 680bhp and 900nm of torque.
This is the later model, similarly to the earlier versions has 2 ECUs, both of which need fine balancing. The difference is these newer MED17 units are tuning protected meaning most people have to remove both ECUs to work on them, usual cost around £5k for tuning. However we have invested in a specialist interface to save on the man hours of the process on this particular type of setup
