Quick ? for ya Jeff, you recommend T'ing off the vacuum line going to the BOV to get the reading for the boost gauge?
Or is that just because its there?

Ive got a vacuum mani with 4 ports and was just going to T off my brake booster line and the wg,bov,boost gauge and 1 more(missing something) for the last one...

Or is going off the BOV source recommended?

 

Yup thats how I do it mostly, but if you have a vac log manifold definatly go off the brake booster and use all the sources off that. However I still would have a dedicated source specificaly for my wastegate from the intake manifold.

 

Aweosme, everything boost related will have its own untapped source off of the vacuum mani

Thanks
