Probably get some hate about this but needed a gauge to verify my boost without apps since they all reported vastly different numbers from 3psi to 24psi which is impossible.
Gauge reports correctly and verified I’m making the correct amount of boost and it holds strong...
For those interested I tapped into the inter cooler map on the passenger side using the p3 boost tap for the n20/n55 engine, the block works but i needed different screws than what it came with
