my astra has sevier turbo lag, the turbo dose not come in until 10.000 rpm, but when it dose it seems to be fine, it also has no power at vrty low revs can this be adjusted.
Had a few turbo bearings go in these,take off inlet hose and feel for play in turbo impeller shaft,may be worth plugging in a code reader too for a look,good luck
