I just made it through all 8 pages of the mod post. That looks like the answer to my problems. Hooray! I'm not an advanced mechanic, but I think I might be able to do this mod.

So in the end, what were the parts required? Just the pressure actuated wastegate controller and the EGR cutoff plate and the various fittings and tubing, from what I can tell. Two questions: What was the final verdict on the best actuator to order? and Where was the best place to connect the actuator vacuum line? I think it was the predrilled hole in the intake next to the cruise control unit?

I am really grateful for this information. I love any solution that makes a system simpler and less prone to failure!
