Did a log of block 11 this morning on the way to work, 3rd gear WOT from 2000rpm to ~4500RPM.

I've just got home and graphed it, and it looks like I have a constant overboost. The actual reading is about 200mbar higher than requested. It was remapped on the standard KKK (blew) and I have upgraded to a Stage 2 MD376. I haven't had the map adjusted yet, but I would have thought the actual and requested should still match? Do I need to adjust the actuator somehow?

It doesn't go in to limp mode mind, and feels pretty rapid!

Needs re-mapped and or VNT actuator checked and adjusted.
