My car is Only showing 7-8 psi of boost on boost gauge ??

[ClarksGT350]

Do our digital boost gauges read low or is there an issue with my car ?
Took the car out today, it feels strong but no matter what gear I’m in the boost gauge maxes out at 7-8psi at full throttle.

From the reading I’ve done our blowers should make 12 psi stock. I have a 2020 GT500
Do you think something is wrong, if so what could it be ?

thanks for any help

Sounds like you have a problem. Is it down on power? I think there were some bad pulleys out there. Someone else can chime in.

Thank you for the reply and especially for the video. I guess it’s just an I D 10 T error on my part.
My gauges reads just as yours does.
Gauge max shows 30. Half way back would be 15 then another half of that is what your gauge shows and mine does also.

Try some race gas. Maybe you got some bad fuel and the ecm is holding back some power... Also, are you experiencing any belt slip? That would certainly cause that issue

Car is perfect. Brain fart is all. Each increment on the gauge is 10 psi.
I was thinking it was 5
