hi, is it worth getting the dsg remapped if i was to to remap the car? and has anyone had it done to the above car, thanks

forgot its a 2012

Also interested as considering a remap for both engine & gearbox , mines a 62 plate 170 dsg diesel twin hatch 

would be interested in the differences / improvements / drawbacks 

any  recommendations in Hertfordshire as to who to use if I did take the plunge 👍
