I haven't looked at the logs but what you're experiencing doesn't necessarily have to be boost oscillation. Could be you're just loading your engine too much at a high gear. Do that in a subaru at high boost and Boom...
If you post the graph, you'll get more responses. Especially from people at work like myself
