Aha!

I have exactly the same prob on my 147SS, before remap 135bhp, after remap 147bhp, changed lambdas and airmass - no effect, check timing - no problems, check vacuum operated inlet manifold no problem there, car feels quick as hell on the road, then the car keeps up to my 175bhp Reddot Mapped GTV TS, maybe its VDC after all.

No VDC problems with my 147 GTA on a dyno. It did display an abs woarning light whicj cleared as soon as I drove off. As I understand it VDC works by comparing the steering angle and the yaw. I can't see why being on a dyno would make the VDC kick in. If it did you would see the warning light flashing and changes in road speed, which (I assume) would be noticeable to the operator.
