2004.5 egts and boost

[JeOsbolt]

It’s still acting stupid, tonight it wouldn’t even blow a puff of smoke on acceleration and still got u and going like normal egts about the same maybe a 200-300 cooler than the normal 900 degrees

So problem still there, but I’ve noticed the when the l oh ad factor and egts go up and boost goes down truck feels like it’s half powered and starts pulling to the right pretty hard. I will add that when I’m letting off the accelerator that hissing whooshing sound is there only at a certian rpm 1500 exactly. It goes away as soon at I touch the accelerator. It will sound like it’s got a boost leak as well when accelerating. Rail psi usually stays around 6k to 6500 but when said symptoms arise the rail psi drops down to 5k rolling up to a stop sign
