Looking for boost readings from turbo nipple vs. intake manifold
Looking for boost readings from turbo nipple vs. intake manifold
I've done a fair bit of searching, but THIS topic I have not been able to find an answer for.
Right now, since I figured I'd just see how the turbo itself was performing, I am reading boost with my Blitz DTT-DC off of the turbo nipple itself. Boost reads just fine, and the car feels good with my Hallman Evo RX kit set at around 1.4 bar. (20.3psi) ....however, I am not reading any vacuum. I'm going to go ahead and cap the turbo nipple and read the boost off the intake manifold like most suggest, but I was wondering why I wouldn't be reading any vacuum off the turbo nipple, could my Blitz be on the Fritz? I've installed several of these without issue, but there's a first time for everything! Thoughts?

You see vacuum only after the throttle. The turbo is upstream.
