slow boost raising

Hello mates,
excuse my bad english, i'll try to make the problem as understandable i can.
I run a stock engine without a catalyst and at around 12psi using an adjustable actuator(not sure if it's HKS)
My problem is that althought in first and second gear boost raises normally, in the rest of the gears the 12psi are not achieved early.
In simple words the few times i had fuel cut(very cold outside) it was at around 6000rpm not 3000-4000 witch is the usual i think.
So with little load (1st, 2nd gear) it has no problem and hits 12psi instantly, but with bigger load it tries hard to accelεrate.
thank you all in advance;)

What RPM are you hitting full boost at in 2nd and 3rd? also what other mods do you run? FMIC? air filter relocation?

i don't remember exactly, but i can answer this tomorrow or the next day.
standart ic, just an hks filter behind the drive-side light (left side drive). The efi pipe is still there
