More of a flywheel issue with them to be honest but, at 81k I should imagine it will have had a clutch if not will be ready for one, clutch and flywheel replacement cost me £800, not trying to scare you off a remap at all as I think its a must have to be honest, as Paul-psa says those tuning boxes don't seem a bad device nowadays I've always prefered a remap don't know why though as these little boxes have come a long way since a few years ago when they used to cause faults on your car, I guess I prefer a map as can tune the car to your mods like I have egr delete, 2 1/2 straight through exhaust and a filter so it was mapped accordingly, also when I get dpf removed a stage 2 will get me the best power squeezed out of it where a box doesn't know these things and the software for them needs writing out the ecu.
