Strange whining
 

And another issue has cropped up. There is a high pitched whine when I put the foot in it. It almost sounds like I'm running twins. The noise is one pitch...unlike the turbo which goes up and down this just stays level but sings right along with the turbo.

I have a video I took if I can upload that. Just turn up your speakers you'll hear it

Hope my turbo is going out :)

Exhaust leak or boost leak!

Thanks I'm gonna go round and check all the couplers bolts and clamps this weekend
