As above a remap at that mileage is not an issue as long as the engine is working OK. Depending on what map you choose and the previous life of the car the clutch may need sorting in the next 20-30K miles. Quite often the clutch may start slipping on higher mileage cars after they have been mapped. As the clutch comes to the end of it's life the clamping force and hence capacity of the clutch to transmit torque reduces.
It really does make a Good difference to the way the car drives. My 130 AWX Passat used to run 210bhp and 345Lb/ft of torque and it had done as many miles as yours.
