GTR only running 0.25 bar of boost?

[OohArrGTR]

Hey, i have a boost guage in my car and when i finally got to get stuck into driving when boosted hard it cut off at 0.25 bar. The stock boost controller is in place and has no boost restrictor on it.. so im wondering what is the problem?? any ideas people and how i could fix it??

Check and see if the catalytic converter has collapsed in on itself, otherwise maybe a boost leak of some sort?

are you sure the boost gauge is working/hooked up properly? I'd check that first.

If it's the stock one on the speedo, it reads in mm.Hg, so you have to multiply it by ~2 to get PSI... If not, what everyone else said.

hey, i just spoke to a guy and he thinks firstly check my blitz guage.. hook up another one quickly and put it through window and check the boost.. if thats still 0.25 bar check the pipe from the wastegate actuators to the stock boost controller... he seems to think it has had an aftermarket one on it and guys left the pipe off ?? sound right ??
