With the last round of upgrades to the cummins in my 93 Dodge 1 ton Dooley, It will make 33 pounds of boost. That's about double what it originally made. Am I looking for trouble?

Modifications include a bigger turbo, bigger injectors, turned up VE series pump, four-inch exhaust.
What is the most boost that these engines can handle and remain reliable?
What are the common failure modes? I have an EGT gauge.

Thanks, Joel
