Boost gauge for jb4

[Krazysupra2021]

Hey everyone quick question what's best boost gauge to use on jb4/most accurate since get different readings on different gauges ecu boost shows me about 15 16 psi wide open throttle boost 1 gauge shows me 20 to 22 psi wide open throttle I am running map.2 with e30

The boost 1 gauge. JB4 essentially is an ECU fooler if ur running map 2 or map 0 you will have 15 / 16 psi of boost won't change. This what the ECU sees in term's of boost. JB4 tricks the ECU to add boost so the ECU thinks it's pushing 15 / 16 psi but actually it's pushing 20 to 22. but still not 100% sure

ECU Boost is the boost ECU is SEEING. It's not real boost.

Boost is chargepipe

Boost 2 is manifold
