162hp increase,with a TDI i woudlnt expect it to cost a huge ammount to get that power as it would on a petrol NA or even petrol turbo car,from what i gather a diesel can handle a good ammount of boost,so for that 162hp gain i suppose they changed the turbo,intercooler,exhaust,induction and with the bigger turbo the ECU being tuned again with a bigger turbo would have gained a nice ammount of power
