A reduction of boost or a bigger turbo.

Compressor surge will kill your engine & turbo.



Eliminate your lack of boost control (you should NEVER see a .3 bar spike EVER) otherwise you risk popping something.

Has this car been verso'd?
Does it run any non standard boost controller (i.e a boost Tee)?
Is the boost control plumbing correct?


Until you have it looked at, avoid the spiking by lifting off a little as it builds boost.
