check air filter is clean and not blocked,check turbo and intercooler hoses are not split or collapsing when accelerating,make sure also that intercooler itself isnt damaged and leaking air? if all ok check that timing belt hasnt jumped a tooth and put timing out. [have come across this a couple of times]
