Question pulsing hesitation at around 2500-3000 rpm

on a uk99. ONLY on full throttle . at around 2500 -3000 rpm .
eg
i put my foot down in 3rd or 4th gear, and as it gets to around 2500 -3000 rpm, it hesitates .like a juddering pulsation feeling. and then it continues onto a smooth power delivery...
anyone
any ideas??

Mine does this under light throtle when the car is cold. Goes away when the engine gets warm, feels like the turbo wastegate actuator opening and closing which will increase then decrease the boost from the turbo.

Agree with the other poster, sounds like the plugs, assuming the idle is ok, (which could indicate a dodgy maf). Get it checked out.
