Hey guys.
My vy v6 supercharged ecotec is haven issues.
It will start and idle fine every time but when u give it some acceleration in park/neutral or underload it starts to splutter and carry on. Seems to be when boost starts to come on at around 2000rpm. You can drive it at idle and will go but any load then problem happens. I don't think it is a ignition fault as it had new coils, plugs dfi module. leads have been checked. and new fuel filter. I have checked fuel pressure at the rail and it's 45psi doesn't go up or down no matter what u do. There is no engine light on at all. When it is spluttering there is a bit of blackish smoke from exhaust. Any help would be great.
