basically correct the ecu has to be removed on the 2.0 cdti and a custum map written
but there is also a code to overcome before they can rewrite it not every mapper can do this
you have just been fobbed off they have not done it as there is no gain what so ever
if you had turbo problems you would be seeing large dips in power and as the dyno showed
your car is fine and putting out the correct bhp a couple of bhp either way is normal
so my conclusion is no job has been done they are fobbing you off and charging you for there time
i would only use a mapper who has mapped a 2.0 cdti 2012 to 2014 as that's when the ecu gets tricky to map
and the ecu has to be taken out
most likely trading standards for you mate
get them to put the standard map back on get your money back and go somewhere that can and has proven they can do it
