its more liklely the driver that will destroy the clutch than the remap. Having more torque means people get lazy with gear changing and dont change down when they should, ie at motorway speed, the car once mapped will pull very hard in 6th, so no need to change down, however doing low rpm high gear accelerations means that peak torque is applied to the clutch for a prolonged period.
if you change down, raise the revs and let the power get you moving you'll prolong the life of the clutch.
