Well, our dual port wastegate has a rubber seal in it, and i tore it trying to adjust the rod. I plugged one of the ports and it seemed to fix the problem, do you know why they even have two vac ports on them if you really only need one? I was just going to try somthing different with the wastegate. I just replaced the turbo about 1200 miles ago and the oil line that goes on the back had one of the bolts wiggle out causing the oil to go onto the back of the engine instead of back into the engine. Long story short....Fried Turbo. So I pulled it back off, and going to have it rebuilt again.
