OK so i put a new turbo in my 2000 atw a4, now it doesnt boost really. Sunday night when i got it done it boosted once and that was to 10 pounds. Then i had no boost after that. Vacuum is normal how it used to be with the old turbo. I checked the n75 and its still good. I had the vacuum line from the n75 to the wastegate disconnected and still couldnt get any boost. The actuator isnt stuck. I checked over every intercooler piping from the turbo to the throttle body and theres no holes, or loose anything. I tightened up a couple of the vacuum lines and actually had boost for about 5 mins, then got to a stop light and had nothing after that. Im stumped and annoyed.

Anyone know what could possibly be the problem???
