Technical Punto GT problem

[Punto_GT_CRO]

I was going to buy Punto GT tomorrow from my mate.

I need help. Car is in immaculate condition, great and fast car, but my friend told me that he had no turbo pressure for 1 minute two days ago

Car is completly standard (no chip, only K&N cone filter), turbo does not smoke, turbo pressuse is normal now.

What can be the problem?

Thank you.

Could be a number of things, split pipe, boost leak, actuator, standard boost controller playing up.

See if the injector light stays on when the car is started and running if so this will indicate theres a problem somewhere.
