with the stage 3 tune is there anything i need to do to my defender. At the moment my td5 has a stage 2 tune with a bigger inter cooler and heavy duty clutch was looking at putting a vnt turbo in soon as i think im still running the original turbo and have done about 280,000km stage 2 tune was done by another company but it's not as much of an increase in power as i thought it would be still struggles a bit in a good head wind and with over taking i am also running a disco transfer box
