I know I tool a glance and it showed 20 PSI and this video confirms that it'll hold 20 or around PSI:

Skip to 2:07 for gauge view where it shows turbo *not my video*:

Ambient temp was 60 and intake temps were 115, wonder if it was cutting back.

I was thinking of getting this AFE, but the numbers make no sense on their gains

I’m in Arizona and it was triple digits outside, still getting the boost to hit the full 20psi mark when punching it. Not impacted by temps here… 2900 miles in the ODO 22,37pkg

Are all these trucks stock tune? The fuel will impact many parameters, including the boost values. “Boost” pressure is not a targeted value, so the boost seen is the simply the value required for the engine to meet the Load and Torque targets. Those targets vary depending on boosted air temps and fuel quality (knock). Relatively low boost says the fuel sucks or the turbos are blowing hot air. Ambient temp can be low, but the turbos blow hot.

I'm getting similar numbers on my stock Gen 3, will hit 19 - 20 sometimes, but mostly 17ish redline. Wonder if I have something wrong too if most people hitting 20 constantly. I'm on 91CA, so maybe that's it
