I have a 99 z28 with twin turbos, made with truck manifolds. Getting no boost. Turbos have duel internal wastegate set at 8 psi. Not sure if I have them hooked up right. Currently not using a boost contoller,since I only want to run 8psi, but I do have a manual one if I need it. Here's a diagram I did with photoshop to show how I hooked them up.

Got any bigger pics? Have you checked the manufactures support section to see how they recommend setting up the WGs?

silly question but seen it before.
how are you testing?
are you putting the car under load or trying to just free rev it up to make boost?
