Hello Alex,
Welcome to the forum m8.
If I was you I would wait a few weeks before getting a remap carried out. You want to make sure the car is up to scratch, give her a good service, good set of plugs good oil, good air filter, check all the vac pipe, clean the TB, check the DV or bin it and get an uprated version then get the car plugged in to vagcom and make sure all is ok.
When your ready for a remap just make sure you have a few quid spare to spend on the car just incase the remap brings unknow faults to life. Normaly £150ish will cover the worse, ie 4x coild packs and a MAF.
