Horrid Cars

Hello all..I am Phil and very please to be here...I bought my 2001 WRX last week but have only driven it a couple of times...been too busy moving house!
However..what could this be then...under hard acceleration there is slight hesitation. Its like missing a beat but not severe-more a slight stutter. It only happens on full boost circa 5000+ rpm.

Any ideas please?
