It was the P2006 code. They changed the vacum valve, then reflashed and resteck to ECU. It does run smoother. It doesn't have such a loud engine note in the higher rev range with the boost on. It does seem to have more power in the lower end. Best of all the tailpipe has less soot (NOT completly gone) and the MPG is up!
I realized mine would go on with certain temperatures outside. If it was cold out it would go on but the next day it would be warmed and it would be off. Now it just goes on and off constantly that I don't even care. If I decide to sell the car I'll get it fixed, otherwise its just a pain in the ass to have to go into the shop all the time.
