if your 100% positive there is no boost leaks and you are getting chronic coal i would say the turbo has gone tight, due to no oil. when i done a turbo change on my xud, i had oil problems which meant the turbo wasnt being lubricated and caused the turbo to not spool at all, felt like i was driving a nad, and i had so much coal dropping out the back. i would suggest dropping the engine off the mount again, take the air intake pipe off and see of you can get your hand down by the turbo and spin it, if it doesnt spin freely then thats your problem
