You should be able to hear a boost leak that bad. Why not do a boost piping leak test.
Can you get full boost gradually, ie build up the load whilst not using wot. Have you tried to get boost above 5k without using wot ?
I don't see why 5k is the critical point here, unless your boost curve cant make max boost at lower revs. A boost leak will leak at 2k 3k or 7k . If you have 2 bar at 4k and suddenly not at 5k then i don't think you have a leak.
IMHO of course.
