Does anyone have experience of the pros and cons of fitting 1.222 ratio disco transfer gears in place of the 1.410 ratio gears into a defender TD5 (2004) transfer box. The vehicle has already had a stage 1 retune to lift the power to 170bhp. Specifically I'm interested in acceleration from start when pulling loads up to 2 tons and overall crusing power when both towing and not towing.
