good thing i checked the cooler piping before ordering a new turbo!! the cooler piping just under the airbox had blown where it meets the stock piping but only to the side and not entirely off so it was still running but terribly and not boosting. i reconnected the pipping and the idoling returned to normal and the black smoke stopped after a few seconds. i took it for a drive and its boosting but ht ecar is sluggish and miss fireing. i am guessing this is because the spark plugs are in ruins after flooding the engine so much and so many times????? so i will buy a new set of them and see she returns to her boosting best
