10PSI Boost Normal?

[Justin]

Hey guys. Just did some spirited driving and I realized That my 2022 SI's boost is capping at 10PSI. I came from a 17 SI which easily went up to 15 PSI all times of the year.

Could it still be in the break in period?

Here is what the driving conditions looked like:
Outside Temp 20-40 F
went all the way up to 5.5k RPM
Car was at operating temperature
Car quickly gets to 10PSI and flatlines.

You mean you are only getting 10 psi ?

Firstly, this car builds boost into higher rpms, if you are in the break-in period you likely aren't maximizing revs (which is a good thing), max boost is hit at higher rpms. Secondly, if you are in cold weather country many boosted modern cars will vary boost based on intake temps to provide consistent power levels - lower boost in frigid temps and higher boost in hot temps - that evens out the power production .
