What causes turbo lag?

This is caused due to the delay in the engine block to produce sufficient exhaust pressure in order to spin the turbocharger and force compressed intake air into the engine. Turbo lag is usually more perceivable during low rpm since exhaust gases and, consequently, air compression is at its lowest.
