Been covered lots I no sorry but..........

I have just fitted a FMIC to my AUM and I can now hear a very high pitch whistle.
I've done a search on here and some ppl refer to the spooling of the turbo as a whistle so I'm confused.
I have always been able to hear my turbo spooling(I love it) and the DV does a slight (dump/swoosh) but as I said its a very high pitch whistle.
Thort it was the radio at 1st poss electrical but it's only under boost/exceleration and defo coming from engine bay and not speakers lol.

Is it a boost leak or just the fact I can hear the turbo more because of the FMIC???

But as I said I have always been able to hear my turbo spooling and this is different.

Something isn't tight enough and your loosing boost....

Nice1 mate. Thort as much but just needed a second opinion. I'll get checking all clamps ASAP and hope its 1 of them rated than a burst hose somewhere.

When I fitted my forge FMIC could hear the turbo whistle slightly louder but could be a boost leak.

Is the FMIC still using the original charge pipe to pancake?

[cooki]

Right investigated this a bit more today and the noise is coming from the t.i.p/induction kit?
Removed the filter to see if that was the cause and the noise was still there coming out of the MAF sensor??

[cooki]

Any1 any idea??

[cooki]

Has any1 at all got any input.can it still be a boost leak cominf through my MAF/induction filter or is it just an extremly loud and anoying tubo whistle that ive never herd before??

The MAF is in the pathway of the intake airflow - that's what your hearing from that area.
You might still have a boost leak - especially if you didn't hear it before installing the front mount.
I recommend checking all the joints or even getting a smoke test done at your local tuner, plus it serves as reassurance and cast away any doubts you may have.

just re reading to try and help, did you remove the DV at all and then reinstall the wrong way?
when its the right way you get the whoose/dump noise, when the 'wrong' way you get a loud chirp sound...

[cooki]

Thanks guys. Dv is in correct way as it still dumps nicely and can be heard through the filter the same as the whistle.

I have checked all joints of the fmic and every other boost pipes i can see and find but still cant find anything.

Strange thing is that i have just done a journy and the whistle wasnt there. Even though it has been there all day whistling away???
