Make sure you use a tuner who knows what they are doing with these new ecus, like Rhyso said they need opening up but also need to be extracted from there security mount which have shear bolt plus the ecu is glued and sealed. Over on the mk5 gti froum there is a topic on damaged ecu from heavy handed removal.
I dont think APR do TDI maps?
IMHO I would go see Craig aka The Doc I know he has done many many of the anit tune ecus and has a nice clean method of getting the ecu out and open, plus will fit new shear bolts.
If your shopping around just make sure one of the questions you ask the tuner is what method they use to remove the ecu, give Craig a call first and he will explain the whole process to you.
