intermittent boost

[40BelowSummer]

hey quick question...I did some work on the SHO a few weeks ago and havent had a chance to troubleshoot this new issue much yet
Lately when I drive the car it sometimes won't have boost and the BOV's don't sound correctly
Then, on some of my drives, it will be completely normal build boost and I can hear the BOV's.
Is there anything electronic or otherwise that could cause this intermittent condition?

Check boost controller reference line (it’s a small tube located on the **** hose which goes over the engine from the back turbo)

Check the Zip tied hose in the pic. Had a similar issue and that hose was disconnected.

Next check after the simple hoses is look over your noisemaker pipe. Mine recently failed, you can see the oil residue on mine. Also had intermittent power issues. New pipe felt like I just tuned the car haha
