I do really think the vanes on the turbo are stuck or misadjusted.

to see if the vanes are stuck use a mitty vac and watch the arm this will confirm that also if you have looked in the link for the u tube video the vnt rod is smooth but the vanes are not .as for the injectors just for your info if the car starts normally hot and cold and on tickover how can you tell they are okay under load????., you can do a leak of test yourself.i no it may be awhile before you get the codes again but it will help us to try and help you . hope that helps.
