I had “The Tune” applied to my 2.4 TDCI two weeks ago and have since had the opportunity to test it on long motorway runs, country lanes and even Central London. The modification is transformative. The increase in torque and power is very noticeable and sits in that part of the rev range that gives you the choice either to change gear less and let the increased torque push you along smoothly at lower revs; or drive harder and enjoy the increased performance. Either way, big smiles all round! Many thanks.
