It does depend on alot of factors.

I got 322 stock

So they defo come in different forms.
Age and if the turbos have been swappped due to wastegate issue will have an impact
dyno set up - some over some under read
quality of fuel and the age of fuel
ambient air temp

also (someone may need to shed more light) but i think tire psi can also affect dyno?

Anyway if you get the good end of all these factors your bhp claim does not seem unreasonable.
Good for you!
