The pressure maxed out at 200 then dropped to 120 at that rev count. I can only assume the hpfp was the reason why we couldn't get more than 316bhp out of the experience. In standard mode it's fine, but means it can't be remapped. Do you think it's the hpfp or something else
when you have a long crank start (videos on youtube) ....this is a sign of hpfp failure...
not making the power expected can be lots of things...you'll need to read codes for this...
getting an engine warning light aswell... can be lots of things....from vanos to boost leak, to carbonisation of injectors/ intake valves, the list is endless...
