Got the new turbo in. Adjusted the rod length and set screw. The rod stops moving at 18inHg. I also replaced the boost solenoid. Before replacing the solenoid, the car smoked like nobodies business. Now it runs fine, without smoke.
I hooked up the VAGCOM and watched the graphs - reset learned settings. The boost runs low at idle..If it wants 900, it is getting 750. The air intake is only half the calculated value.
I hooked a vacuum gage into the line going to actuator, and a vacuum gun to the actuator. By hand I reproduced the vacuum reading from the gage. Trying different amounts of vacuum, the under boost didn't change.
There aren't any leaks from turbo to intake.
Not throwing any codes.
CCV tube from valve cover to intake is off. Waiting for new heater to arrive.
Any ideas?
