MAP sensor port on intake
I previously had my map sensor signal referenced off the brake booster line.
I noticed however, that under light boost- like 3psi, the signal oscillates like crazy and freaks out. I can see my needle flapping on my boost gauge. Braineack once wrote that particular port is turbulent and my boost gauge may be confirming it.
I want my MAP signal to be stable as hell. I have a bunch of stock ports capped off on my intake. They were originally used for emissions. I have no clue why the hell Mazda placed them where they are. I mean, a few of the ports were actually connected to other locations on the IM. One had a check valve between ports. What the ****?
Is the consensus that it would be safe to use one of those stock ports?
Or should I use my hole saw and make a fresh 1 inch port for my signal? J/K I mean a 1/4" port.

i use the port that was for the pcv on the valve cover into a vac block
if i were doing it over i would invest in an AEM sensor and tap it right into the intake manifold plenum.
i found that the ports on top of the 1.6 intake manifold that were meant for the purge solinoid or something didnt read boost on my mechanical guage... so be careful
