you will be getting boost but losing it though the cracks in the housing,causing lag,until it boosts harder.
whats it like when you take your foot off the revs mid boost...does it take a bit of time to boost up again?
msd as said above check evrything as ever their usual faultless service, n it came back with a clean bill of health, but was suggested the waste gate penny may not be sealing correctly!!!
A cracked exhaust housing may be a good call as i know colly sufferd with this only the other week on martoons rollers, so it may be may next port of call
mid rang boot when you let off then power down again it seams ok al be it may be slightly laggy,
higher up the rev range when hard on boost its fine and when you change gear it spools up hard again
