you want to chip the TD rather than go the route of tuning boxes, get much better gains, as the TD was de-tuned for Vx, and chipping it brings it back to full BMW Spec.

Also is it an auto? If so, your going to need to replace the box with a stronger AR35 as the current one won't last long with that extra power going through  :y

Have box fitted to mine. Had no problems what so ever with it. Pulls very well indeed. No clouds of black smoke or boost problems.  I would double check you have it connected correctly. as far as i know the amount of boost is controlled by the wastegate, so if yours is overboosting maybe your wastegate is not opening correctly/sticking but you only notice it with the box on. Worth a look if nothing else  :)

Is your box a plug in type or wire-in type ?

TD has a mechanical wastegate, not electronically controlled, so genuine overboost is a weird one.

How do you know it is genuinely overboosting?

What does this thing connect into, the boost pressure sensor?

Sounds a bit naff to me to be honest particularly seeing as how cheap a new map is for them
