Combo Van 1.7 TDI Very low power problem Y17DTL

I have got a 2003 combo van it has the 1.7 litre turbo diesel engine the engine code is Y17DTL.

The problem i have got it is really lacking power, i am getting no error codes from the ECU at all and there is no smake coming from the exhaust.

So far i have changed the Mass Air Flow, The boost sensor and the vacume pipes and i have also had the turbo off and it appears to be perfect conditon for a 70k van.

I thought it might be a cat problem so i took the cat off and ripped all the insides out and it is still doing the same.

Can anyone else give me any ideas to what else it could be?

If you need any more details of the test i have already done let me know.

Thanks
