My missus drove a VE Omega and said it was a slug. It has the same 4L60e box as the ecotec, makes the similar power to your 190 alloytec (180kw/330Nm torque). She said she didn't have the confidence to nail it at an intersection to try and get a gap like she could in her own car. Funny isn't it. Admittedly, her VS goes a lot better than stock. I drove VX L67 (standard supercharged engine) recently and it wasn't any faster than her VS.
