Is it a good idea to tap my boost gauge line to the charge pipe before the tb? I know it won't read any vacumm, but would it be accurate?

 

That's a good question. I'm curious too... I would think yes it would be accurate.

bump!

 

Errr... it will be accuarate at full throttle.

At partial throttle, you often will have more boost in the intercooler pipe than you do in the manifold; with a smaller turbo, you could easily see 5-10 psi more in the intercooler pipe when you're at part throttle.

So, the max boost will read correctly, but part throttle will not.

Also, having a vacuum gauge is a great diagnostics tool.

That's true!
