9200i 2004 turbo "chuffing" at speed

9200 i cummins 2004, 612k

At speed above 40 bob tail the turbo kicks out at medium to full throttle. The truck is governed at 62 mph, so its hard to see if I can keep the turbo pulling with light throttle, before waste gate???? kicks out. It was real bad when I started driving(turbo would fluff at speed), but improved as I drove 250 miles to New Jersey. The air pressure on the bottom gauge was 140+ psi and after two hours it started kicking out at 138psi. The truck has been sitting for 11 months. Also, you can feel blow by at the exhaust pipe/turbo exit interface at idle. Could it be just as simple as some gaskets??? (probably dreaming on that)

Any fair price and good mechanics in North Jersey? I wouldn't mind going to PA.

 

Ok, I looked at it again the pipe on the exhaust side of the turbo is lose the "lip" is off. So the clamp is ineffective. Sigh of relief. It might be a cheap fix.
