Default Stutter/running probs

Hi Guys

Had an ongoing problem with my 55 STI.
Its started stuttering and holding back even when warm.
Mainly in low gears at change over 1 - 2nd, 2nd - 3rd.
Mostly when cold or after its had a good run.

Ive had an ECU reset twice, cleaned MAF sensor, just had 40,000 service with new plugs, coolant, fuel filter.

While at Scoobyclinic yesterday having the above it also had a dyno run and is running fine with 297bhp and no signs of any problems on the dyno.

What should I check next ?
Sensors ?
