Could i have put my turbo together incorrectly

I am having continuing issues with Airflow through engine. This is a very much a stab in the dark but I have the sense that the volume of air being drawn into the engine at low revs is incorrect.

Unless I am wrong,,,,,,, quantity of airflow is contributed to by the Turbo which is driven by exhaust, whilst the speed at which the turbo is driven is influenced by the position of the vanes in the Turbo. and thus the positioning of these vanes directly influences the quantity of air drawn into the engine.

When I was reassembling the turbo could I have put these vanes back incorrectly, so that they were out of sync with the lever which operates them thus, only at midpoint would they be close to their correct position.

I say this because the car is beautiful to drive at about 2500rpm in 6th at 120kms which is pretty close to mid ways...

can this be diagnosed using VIDA.....

Any advice or info Please!!!!!

Tony.
