Mark came to Tunit to improve both the power and most importantly the fuel economy of his Range Rover. The power was increased from 271 BHP up to 324 BHP. That all important torque was also boosted from 472 lbs/ft to 563 lbs/ft. The Range Rover will now regularly outperform other 4x4’s both on and off road, greatly benefiting from improved acceleration and reduced flat spots. As someone who regularly tows a horse trailer the Tunit allows for easier towing and carrying of heavy loads.
