That's the turbo air in hose ( the big one). I believe the little one is the pcv hose.
Turbo pressure does not go through those hoses.
If this is a tdi, the usual cause for lack of power, is due to the turbo vanes not moving. Which causes no boost.
Have someone check the vanes for correct operation (vacuum pod, vacuum solenoid & hoses).
A bad Maf sensor can also cause lack of power, so have them check that too.
