Where is the best place to tap for a pyro? the discharge casting on the turbo or the down pipe?
Also how about the boost gauge?Turbo discharge or the intake manifold?

 

Heres where to put the pyro. http://www.piersdiesel.com/TechPyroInstall.htm
Boost goes in the intake, at least 3 ways to do it:
1; Boost bolt, available from many mfrs in links. Basically you remove an intake bolt, replace it with the boost bolt, which is threaded for the boost fitting.
2; Find a pipe plug on the intake, usually on the side, pull it, use whatever reducers are required to get it to the size of the boost fitting. Mine was right below the air horn, next to the IP, and was the right size.
3; Remove, drill and tap the intake air horn, to the fitting size.
Enjoy.

 

Boost port here. Injector lines removed for clarity, you can get at it without removing them.
