Thanks all for the answers.

Now that I'm thinking of it, I did use some rust penetrant on the bolts farther down on the downpipe. However, I didn't use much, and it looked like the actual housing was smoking. Knowing that new ones often do is a relief.

Do my idle AFR and vacuum look correct?

I'm going to try the car under load today. Since I now have a t28 in a car that was tuned for a t25, will I have to retune? Right now the wastegate actuator is vented right into the turbo, but I do have a boost controller.

Should I check my AFR under boost as is, and put in the controller if I need it?
