Why does the acceleration hesitate when then gas pedal is floored? on 2001 Volkswagen GTI

Once the car gets to about 2-3k RPM when the turbo is REALLY starting to spool, the car hesitates almost like the injectors are clogged or not enough fuel is making it to the motor possibly. I was told that the ECU might need to be flashed or tuned but I'm unsure. Anyone have any ideas? Thanks!

I would look for codes first. Would give you better direction to go. Many things could cause a hesitation like this. Can you get more info like codes?

Nope. The car isnt technically mine yet but the only other information I can provide is that the engine light is on, apparently because of a missing o2 sensor.
