The surging when travelling at around 3000rpm is probably just because it's the point when the turbo boost really gets going. If you're cruising at 75mph (=3000rpm in top gear), then the slightest bit of extra throttle causes the turbo to spool up a bit, which makes more exhaust gas, which causes the turbo to spool up quicker... etc. You get the idea! It can be a bit of a challenge to hold it at that speed.
However, most MY99s do seem to surge a bit between 2500 and 3000rpm on light-medium throttle when cold.
