A stage 1 remap isn't scary enough to warrant a brake upgrade really, but it's a good mod regardless. A good panel filter in the standard airbox and using decent fuel (vpower) go really well with a remap. If it's not been done before your throttle body will need cleaning/adapting to get the most from the tuning.
Your factory DV might last a week or two.. but they all break in the end, even on unmapped cars. Some people use a DV from an audi tt as it's a bit stronger and cheaper than a 007p but without the bling.
if yours is a high miler on the original clutch then it's probably on it's way out anyway, but the extra torque will make it start slipping sooner. As a general rule if you're under 80k miles and your clutch is still strong or has been replaced already.. then you -should- be okay. But then again sh!t happens

a 51 plate means aum engine code, so you suffer from dodgycoilpackitis. They can give up literally a mile up the road if they're a bit ropey anyway. You also have a complicated system of vacuum lines which are prone to leaking, same with breather hoses.
Boost hoses can work their way loose over time and develop small leaks which become more apparent after a remap with so much more pressure in them. Usually you can just clean them up and re-tighten them if that happens (with a 1.8T anyway, tdi ones break completely sometimes).
Existing underlying problems with the engine are usually the biggest issue with a remap. If the car isn't running right in the first place, asking more from it with a remap can amplify the problem and lead to disappointing power figures

Cam sensor, o2 sensor, maf, temp sender.. the list goes on. In the most unfortunate cases a car might have major hardware issues.. cracked manifold/turbo, split downpipe, broken cat, blocked oil pump or even internal issues. So if you're not running right before the remap, have any fault codes/warning lights or even suspicions then let us know.
Sounds scary, but there are loads of remapped cars out there running fine and r-tech check alllll that stuff for you. There's even an office with seating (but no lighting yet

) been built at the workshop for you to wait in while its done now lol.
No more standing outside in the cold lads!
