Whistling noise boostin

[inspire]

Put a FMIC on the car, had leaks, pretty sure I fixed all leaks runs good again. Might be a stupid question but now under boost the car makes a very loud whistle during spool up. Is this normal or is this still a boost leak or is there something more to it. I'd rather look stupid and ask then look stupid on the side of the road. Thanks

Car did not whistle like this with stock SMIC. Bigger core maybe?

Still sounds like you have a leak. Boost leak test it. That's a simple way to find out.

It is indeed a boost leak. Pipe keeps coming off when I start to spool up. I am fixing as we speak. Thanks for replies!
