    Recently put in a ADD FMIC kit on my truck. Ever since the install I get a buzz almost as if I have a boost leak. The noise sounds like it’s coming from underneath basically right where your charge pipes are into the front mount. I went ahead and installed a new turbo smart BOV but no change. This noise is only heard under heavy acceleration with boost at about 21-22 psi(Cobb stage 1 91oct tune). Boost doesn’t appear to taper off too fast and power doesn’t drop off either. Anyway I’m planning on doing some boost leak testing but just wanted to reach out if anyone knows the turbo inlet diameter sizes?

    They’re 39 mm turbos but I haven’t measured the inlet to see if it matches.
