My 2020 N PP boost never reaches 10 psi. I see videos of others routinely hiting 12 or more. Should I take mine in? I know nothing about turbo cars this is new to me. 8 psi is highest I can get mine opening it up.

Is that indicated in the instrument cluster real-time or are you looking at the graphs on the touchscreen after the fact? Touchscreen seems to record lower values for some reason. Using 91+ octane?

Im using 93 octane premium always. Its real time psi readings on my dash. I've never seen it hit 10 psi.

I did read one guys was reading 0 on the dash real time. And they said that the dealer flashed their ecu and it fixed it for them. But While I was at dealer I asked about the graphs being wrong. And they looked for an update for it but said there was none. I wonder if its every n that does that or just some.

Mine seems to hit 13-16 psi regular on dash but in the graph it rarely goes above 10

If you want to know what the true boost reading is; either buy and install a boost gauge or invest in a good datalogger.:)(y)
Do you have a good boost gauge? I think it will really help for if I decide to get the REV6 over the AFE Scorcher.

15~ PSI on the digital gauge and 13.8 PSI on the graph was the highest I have seen though under general cruising (not really going over 5k RPM) I see about 8-13; 13.8 registered was at 121 MPH. Only thing different from stock is an aF Takeda Intake.

If you really want to test it you can always get up to about 55 MPH, get into 6th gear and just gun it (you'll definitely hear the turbo spool up, won't really go anywhere but I would wager if that doesn't get you numbers above 10 PSI I don't know what will).

Living with this thing the last few months in FL and our weird weather as of late (58-60 degree mornings to 91 degree afternoon's) I notice when it's colder out you get considerably less boost (which kinda makes sense, colder air is more efficient and you need less boost for the same power).
