Low Boost Pressure

Hey, I got a 2008 F350 6.4 PSD Job 1
Its been a great truck honestly, it has 216 000kms 4200hrs on it never given me a lick of issues other than the normal recalls a rad and map sensor 2 years ago.
It has full egr delete, dpf delete h&s mini maxx tuner running the hot damn 300 but I dont put my foot into it much.
I noticed a whistle/whine if you will comming from under the hood noticed my intake elbow had a crack in it so I replaced that (oil was leaking around it from blow by)
Whistle/whine never went away. Started two weeks ago. Started to pay good attention to boost and what not I've put my foot into it before and never had my tuner beep at me for my high exhaust temp, that tells me more fuel less boost. So I decided to put my foot into my truck today and watched my boost noticed my peak was 34 psi from a dead stop to 160km/h thats not right! I've seen it peak at 48 with my foot 3/4 of the way into it
Checked all my boots no signs of cracking or holes in them no sucking coming from around any of them pulled the elbow off the turbo you can get to it and it spins proper and freely its just not building boost proper....
Hope someone has some suggestions cause im stumped!

Also yesterday this happened twice I was driving forward and tapped the gas and let off the throttle stuck around 1000 rpm until i put it in neutral it slowly dropped in a few seconds. I never though anything of it. Later that day I was backing into my parking stall again just tapping the gas it kicked up to 1000 rpm just about ran into my fence same thing neutral and it went down! No my floor mat wasn't in the way.

Check the firewall for soot. Could be a cracked up pipe. Also clean your map sensor and ebp sensor and tube. They could be plugged with crap.
