Hi can anyone help please??

I am new to this forum and am having problems with my 220 turbo!!
Under hard acceleration when I boot the throttle, I experience a problem with what seems to be the turbo cutting out! Like momentarily hitting a brick wall!! The turbo seems to be boosting fine. My dad is a mechanic and he seems to think that the people who owned the car previousl ha d a re-con turbo fitted and that the vacuum pipe routing was put on incorrectly! Can anyone help with a diagram or somewhere I could get one!!
We have tried the rotor arm and this is not the culprit!! Just a shame cos its a lovely fast car but the cut out is so violent it jolts the car! At a loss to what it could be!!
If you could help it would be greatly appreciated!

Thanks

Woah stop right now! It sounds like you are experiencing boost cut.

Has it got an aftermarket boost controller on it, or has it got the original boost control valve?

You need to get a boost gauge on there to find out what it is boosting at. Maximum reccomending is 11.5PSI.

The ECU cuts the igntion when it sees a boost pressure over 14.5psi as a safety feature. This is known as boost-cut.

Thanks I will try this and see what boost I am running? Any further suggestions greatly appreciated!!

Double check that the actuator pipe is not split as this can cause boost cut as well.
