Paul’s Range Rover Sport in with us for advanced diagnostics and a our DR custom tune once repaired. The TDV6 had previously been to numerous garages to “diagnose” the intermittent restricted performance fault on the dash. Once in our workshop our techs quickly diagnosed the issue to be a cracked inlet manifold a common issue with the 3.0d engines across the jaguar/land rover brand. Once all repaired and a EGR delete kit fitted, we got the 4×4 on the dyno for tuning, the new power peaking at 305.6hp gains of 67hp over the initial run, and a huge 610nm totally transforming the whole driving characteristics of the 4×4 with the new refined torque curve.
