BMW M4 Running Question?

[S800VXR]

Yes I know it's not HSV spelt backwards but does anyone know if the new M4 is restricted power wise from new as my mate just brought a spankers one and whilst nice it didn't wow me going up the road flat out. G Box obviously helps enormously with 8 ratios and fast changing but it just didn't feel brutish. Google mentions nothing and he was not told anything and yes he was in full M mode.

I did say he could of had a new GTS and 10k spare but he is a badge man!
