First post. Hi! I'm helping a friend with his 2003 ALH. He doesn't get any boost at all from the turbo. We've swapped in a replacement MAF sensor and the VNT75, just to make sure those were not the problem. I also felt the actuator move and compared it to one that was running correctly. It feels like it only moved about 1/4 as much as it should. So now I am trying to figure out if the actuator is faulty or if the vanes are clogged up. What's the best way to isolate the actuator and check to see if it is working correctly? Thanks!
