Leon 225 TCS Light

[aaron_2000]

Been running my Leon that doesn't exist for a few weeks now, I've noticed after about an hour, the TCS light comes on. The car has a printout from 2013 for a tad over 300bhp and 340lb/ft, I've been told it's running about 330 now, but without proof I'll assume the printout numbers. Would I be right in assuming this is just a case of the ancient TCS can't keep up with the massive boost in torque? Or is it something along the lines of a sensor? Keeping in mind it only comes on after an hour or so, or under some hard driving.
