ive now adjusted mine to 13 full clear threads from 15....seems to have a little more torque...try that before you get the loom...NB if you do need one, buy it from Famous Four-still OE spec but about £80 cheaper than LR...youll need your ECU tested too...my dodgy loom had fooked me ECU & I had no signal to 3 injectors..send that to TD5 Alive..
