What does the 2.7 V6 HDi gain?
It is a bi-turbo V6 diesel with substantial torque that gains noticeable mid-range flexibility from a measured map.
Does it affect the hydractive suspension?
No. The work is done on the engine ECU and does not touch the suspension system in any way.
Is a remap worthwhile on a car of this age?
It depends on engine condition. On a well-maintained example it responds well, but remapping does not compensate for wear.
