If your hard on the clutch anyway, with rapid starts and riding the clutch a lot then a remap would give it a much harder time and make it wear out/slip earlier than you would expect from standard.
If your a relatively sencible driver then a basic remap shouldn't pose too much of a problem for longterm reliability. You may need less gear changes anyway as the extra torque will probably mean you need to downshift less often as it will probably pull a higher gear.
Beware of the tuning boxes if your thinking of a plug in solution instead of a reflash map, as theres some good ones and some bad ones. The good ones will be about the same price as a reflash but would be good if you plan on changing motors because you could swap it over... These are a chip controled piggyback unit, modifying the ECU signals dependent on several variables (often with different settings avaliable for modest or full gains).
The cheap boxes are usualy just a few resistors to fool the ECU into thinking the incoming air is cooler than it realy is. This causes the ECU to add more fuel which can produce more power to a point (that point being the lack of surplus oxygen to burn the extra fuel) after this, extra fuel consumption won't produce extra power but will produce extra smoke and poorer mpg.
A good tunning box or reflash could see an extra 4-6mpg from a similar paced driving style

Makes complete sense and from my understanding a proper re-map would be a better option. Certainly from my experience of being around RenaultSport Meganes and like you say an increase in MPG is also apparent.
