I need some advice on adding EGT problems in my stock turbo manifold.  I didn’t monitor EGT before, but now while adding the EM3, I want to add EGT.  Is there a preferred location in the manifold to drill to install the probes, and also is it best to add a weld bung, or just tap the hole in the manifold, as it is fairly thick.

Regards,
