Default another boost question

I've had a VDO boost guage in my car for six mo. Just last night boost was hitting 11psi at full throttle. Drove the car to work today and boost at full throttle was back to 8psi. What should I check? Is it normal? Man, hanging out in this forum is making me paranoid j/k....TIA

Default boost will vary based on all kinds of things -- current air pressure, air temp, etc...

I've hit 0.85bar (12.3PSI) on my _STOCK CHIP_ when it was really hot out, and I was on the track.

Generally I don't go over 0.75bar (10.8PSI).

0.7bar (10.1PSI) is generally the specified max stock boost. hitting 11psi is totally acceptable
