LOSING TURBO PSI MPS

[MOSMADNESS]

Hi
Please help?
My MAZDA3 MPS 59 reg sometimes struggles to get to 15psi on boost gage and when it does drops down straight away? If I let off throttle and put down again goes back to 15 psi but after few seconds drops again is this normal or do I have a problem???

Boost leak.

Check your pipes for cracks, loose connections etc.

Also check your intercooler for cracks

You sure its not just the turbo reaching peak PSI then bleeding away with revs? A turbo car wont produce x amount of PSI all the time...

Normal, quick google shows 13.6psi as standard, with some making 14.5psi. This is the peak figure which drops down as revs go up.
