Don't get me wrong, when I hit the right place on the accelerator the car shifts along no problem but I have never had to push down so much to accelerate, it is to me at least very noticeable. I'll give it a few more days and see how things go. I understand that the cats are a sealed unit so couldn't exactly be cleaned through. I was told today by the garage that the car was quite smokey on friday and it wasn't acceptable to give back to me in that condition. After 120 miles drive on the motorway yesterday with plenty of foot down experiments with the turbo I can honestly say that it's hugely less smokey that it ever has been in the 3 years I've owned it.

You have to ask your mechanic those questions,especially if he updated ECU!
That black box is the vacuum reservoir and has 2 pipes.Not unknown for this to crack and loose vaccuum !Connect the 2 pipes together to bypass the reservoir just to test.If no different ,connect pipes to reservoir again.
The cat is a sealed unit but what I meant was if the mechanic checked if there any turbo parts blocking it ,as usually when the turbo breaks,the turbine falls down the downpipe and stops in the cat.
Hang on ,you said that the garage said the car was quite smokey on friday and it wasn't acceptable to give back to me in that condition.Well,they must have remapped it back and reduced the fuel and hence your lack of performance and smoke.Could also be they put a smaller turbo,like a 2056 off a pre-facelift 3.0D and then the injectors were over fuelling the car,so they had to drecrease the fuel amount debited!In anyway,this is very unprofessional and they should at least have let you see the car when finished the turbo replacement ,for you to see if the smoke was as before.On no account should they have messed about with ECU,without asking you first as this has nothing to do with the work you left the car with them for!
