Another big red headache

[Lonestar10]

Well found small leak on boot from turbo so now it gets to 35psi when held to floor at 1500-1600rpms up a hill. Goes to 30psi immediately then very slow climbs took about 20sec to get to 35.
Going to measure boot size tomorrow and go buy some pvc pipe parts to plug and test cac tomorrow when I take exhaust apart.

Also tried old imap to make sure wasn't a sensor issue.
And I would think almost 100k rippums on the turbo should be boosting good.

Question

if I don't find a leak or plug tomorrow could the 1.1mil mile head be the issue? Overhead was done 2 weeks ago. Injectors/actuators replaced in last 4mos so don't think it's fuel related. And everything below head was over hauled 200k ago. Before I bought truck. I'll post pics of overhaul invoices in a bit to show part lists.
