I need help diagnosing an issue with my n26 engine. I have a injen CAI that makes the usual loud "whooosh" but now I am getting some turbo flutter. Could my diverter valve failed? I am also running bm3.

I think I got some more pronounced turbo sounds with that intake. I don't think you need to worry. I get them especially in the low gear / rpm. Usually none when I'm at 5th gear+

I've been running that intake for almost 2 years now, it only just started doing that

You shouldn't be getting any compressor surge (turbo flutter) on the stock DV. Some stiffer aftermarket DV's will give you that and that's normal, but the stock one shouldn't. I would guess that your DV has gone bad.

Yea I would say the same.

I'm getting the same noise. flutter sound n20 also bm3 stage 2 agg. already have gfbv2 on hand bought 4 months ago

On a stock DV, you shouldn't be getting it. I got mine when I went to a DV+ and becomes less frequent as the spring becomes broken in. While it's unexpected, I would only worry about it if you are getting flutter after a WOT release (As in, you build up to 20PSI and release the gas, resulting in flutter) or if you get flutter while you're on the pedal. Run some logs to check your WGDC and boost levels as well.
