GT350 IM install vacuum questions

[Poppacapp]

First off, I have looked and have seen different pictures, videos, etc.

My car is automatic 3.15.. I assume the vacuume line on the bottom of the cai elbow is needed for something but is currently capped off. Didnthe manifold, if1050x injectors and 5C converter. Trans is shuddering slightly on part throttle shifts and short shifting into higher gear also. Car is still on bas tune and I have to do logs.

My question is, does someone have a diagram of the exact vacuum hookups for the gt350 im using the oem GT throttlebody, on an automatic car? I want to eliminate that as an issue before I start logging and revising tune.

Thanks!

Not exactly a diagram, but here is what I did (I capped the vacuum port on the bottom of my CAI, and this is the 90mm TB, but should be the same as stock in all other respects). These were taken at night, so sorry for the image quality.

Much appreciated! I think part of my issue is I am not used to how high rpm stalls drive... much different. Working on part throttle logging now.

Thanks!
