boost leak means it can't hold boost

doesn't high egt means it's lean? if it's rich, the fuel would cool the egt down

If you have a boost leak you'll run rich, so your egt's will drop.
Of course you could be running so rich that the fuel will ignite in the manifold and will heat up the probe, you'll know when this is happening when you see a 10 foot flame in your rearview mirror

If you have a boost leak, your controller will make the turbo work twice as hard to hit full boost. This will make it run inefficiently and spit out very hot air. Even if you are dumping fuel, it can get bad enough that that will not be enough. Plus, the fuel is cleaning the oil off the cylinder walls and that is not good. Go around and check all your fittings and get a leak tester if you can. A fab shob should charge you very little to make it and a service center should charge you very little to test with it.
