my clutch was only 5k old when the car was mapped to stage 2, and lasted 5k at stage 2 before dying, so only 10k miles on it in total!
Jamie, I hate to be annoying man, but off the lights isn't what will kill your clutch, it's higher gears, 3rd upwards that will make it slip.
mine started slipping in 5th only at 3k when overtaking on the motorway where load is at it's highest, then over time it started slipping in 4th, then 3rd, then eventually second by the time it was fully mullered.
