Also seems to be maybe a second delay in planting the boot and power. It's 140bhp. Thanks for reading. Oh had it on vdms or what's its name and no faults logged

could be just the turbo holding back because of how much your pressing the pedal.

e.g the turbo if you press lightly doesnt make pressure, only when its boosting it makes go fast,

see this image for example

so when you lightly press the pedal it goes minus but when you press harder it begins to boost to + pressures.
