Clutch might have been on the way out before it was remapped, in which case it's life would have been even more reduced.
Thats basically whats happened to mine. Got it remapped last week and done over 1000k since and clutch is gone. Getting new clutch/flywheel etc and its costing me just over £750. Thats fitted. And its all upgraded so can take up to 390ft/lb of torque. So £1300 is very expensive I'd have thought!
