Pretty sure I have a boost leak somewhere as my egt's are slightly higher and I'm making more smoke. I cant seem to hear anything leaking over the engine noise or from what I can see I can't see where would be leaking from. Any suggestions as to how to track it down without taking too much apart?

Boost leak on the exhaust side you should see where the soot is escaping. Intake side would be a little harder to pinpoint without help from a friend to help listen while building boost maybe? Use a cone or funnel up to your ear to pinpoint when you do hear it. Or cover areas with your hand for sound changes. but for starters I'd just check boots for cracks. Maybe someone could chime in on if brake clean or something similar is safe to shoot bursts of it around intake? Works well with gas engines and fortunately all of my boost leaks have been on exhaust side so far with diesels and I'm a noob and still learning quite a bit on these. Good luck, Hope this helps
